Give Your HP Laptop a New Lease on Life: Reinstalling Windows

Is your HP laptop feeling more like a paperweight than a powerhouse? Does it take ages to boot up, and programs crash more often than your clumsy friend at a party? Or maybe you’re just looking to wipe it clean before passing it on to a family member or selling it. Whatever the reason, sometimes the best solution is a fresh start – and that means reinstalling Windows.

Why Reinstall Windows? It’s Like a Digital Detox!

Think of reinstalling Windows as a spring cleaning for your computer. Over time, your system can get bogged down with unnecessary files, conflicting programs, and even pesky viruses. Here are some common scenarios where a reinstall can work wonders:

System Instability: Random crashes, freezes, and the dreaded Blue Screen of Death (BSOD) can all signal a deeper issue that a reinstall can resolve.
Performance Issues: If your laptop feels sluggish and slow, even after basic troubleshooting, a clean installation can often restore its original speed.
Virus or Malware Infections: Sometimes, even the best antivirus software can’t completely eradicate a stubborn infection. Reinstalling Windows wipes the slate clean.
Preparing for a New User: Giving your laptop to someone else? A clean installation ensures your personal data is completely removed, and the new user starts with a fresh, optimized system.

Don’t Be a Hero! Back Up Your Data!

Before you dive in headfirst, listen up! This is non-negotiable: Back up your data. Reinstalling Windows will erase everything on your hard drive, so make sure you have copies of all your important files. Imagine losing all those family photos or that novel you’ve been working on! (We’ll cover data backup in detail later, so don’t panic.)

Reinstalling Windows: A Sneak Peek at the Process

So, what exactly are you signing up for? Here’s a bird’s-eye view of the steps involved:

Backup Data: Safeguard your documents, photos, videos, and other personal files by transferring them to an external drive or cloud storage service.
Gather Essential Items: Locate your Windows product key and create a bootable USB drive with the Windows installation files.
Access BIOS/UEFI: Modify the boot order to ensure the laptop boots from the USB drive.
Initiate Windows Installation: Select the “clean install” option to erase existing data and configure the hard drive partitions.
Complete Windows Setup: Follow the on-screen prompts to configure language settings, create a user account, and adjust privacy settings.
Post-Installation Tasks: Install drivers, update Windows, and restore your backed-up data.

“Where Did I Put That?” The Importance of Your Windows Product Key

You’ll need your Windows product key to activate your newly installed system. It’s like the secret handshake to get into the cool kids’ club (aka, a fully functional Windows). Find it before you start! We’ll cover how to locate it in the next section. Trust us, you don’t want to be scrambling for it halfway through the process.

Preparation is Key: Backing Up Data and Gathering Essentials

Alright, before we dive headfirst into giving your HP laptop a sparkling new Windows makeover, let’s take a deep breath and make sure we’re prepped and ready. Think of it like packing for a trip – you wouldn’t want to arrive at your destination without your passport, would you? This stage is all about safeguarding your precious data and grabbing all the tools we need for a smooth reinstallation. Trust me, a little preparation goes a long way.

Data Backup: Safeguarding Your Important Files

First things first: back up your data! I can’t stress this enough. Imagine losing all your cherished photos, important documents, or that half-finished novel you’ve been working on for ages. Nightmare fuel, right?

Here’s the lowdown on different backup methods:

External Hard Drives: These are your trusty sidekicks. Just plug one in and drag-and-drop your files. It’s simple, effective, and gives you a physical copy of your data. Make sure it has enough space!
Cloud Storage Services (e.g., OneDrive, Google Drive): These are like having a digital safety deposit box in the sky. Upload your files, and they’re stored securely in the cloud. OneDrive often comes pre-installed with Windows, while Google Drive is another excellent option. Just make sure you have enough storage space in your cloud account, or you might have to pay for more.
Creating a System Image: This is like taking a snapshot of your entire system, including the operating system, applications, and files. It’s a more comprehensive backup, but it also takes up more space. You can restore your entire system from this image if something goes seriously wrong.

Prioritize backing up your personal files: documents, photos, videos, music, and anything else that’s irreplaceable. Don’t be that person who regrets not backing up their stuff!

Gathering Essential Items: Product Key and Installation Media

Next up, let’s gather our supplies. Think of this as assembling your toolkit.

Product Key: This is the secret code that unlocks your Windows operating system. You’ll need it to activate Windows after the reinstallation. Here’s how to hunt it down:
- Command Prompt: Open Command Prompt as an administrator and type wmic path softwarelicensingservice get OA3xOriginalProductKey. Hit Enter, and hopefully, your product key will appear.
- Laptop or Packaging: Check the sticker on your laptop (usually on the bottom) or the original Windows packaging.
Installation Media: This is what we’ll use to actually reinstall Windows. You have a couple of options here:
- Media Creation Tool: This is Microsoft’s official tool for creating a bootable USB drive. Just download it from Microsoft’s website, run it, and follow the on-screen instructions. It’s pretty straightforward.
- Windows Operating System Download: You can download the ISO file directly from Microsoft’s website, but using the Media Creation Tool is generally easier for creating a bootable USB.

Identifying Your HP Laptop Model: Ensuring Compatibility

Knowing your specific HP laptop model is crucial. It’s like telling the mechanic what kind of car you have – they need to know the specifics to fix it properly. This information is essential for downloading the correct drivers and understanding your BIOS/UEFI settings.

Here’s how to find your model number:

Sticker on the Laptop: Look for a sticker on the bottom of your laptop or under the battery. It usually contains the model number and serial number.
BIOS Settings: You can find the model number in the BIOS/UEFI settings (we’ll get to accessing those later).
HP Support Assistant: If your laptop is still working, you can use the HP Support Assistant software to find the model number.

Network Connection: Staying Connected During Installation

Finally, make sure you have a stable network connection. We’ll need it to download updates, drivers, and anything else that Windows needs during and after the installation process. A wired connection is generally more reliable than Wi-Fi, but Wi-Fi will work in a pinch.

With these preparations complete, you will be ready to start the reinstallation.

Accessing BIOS/UEFI: Configuring Boot Settings for Installation

Alright, buckle up, because this is where we tell your HP laptop who’s the boss. To reinstall Windows, we need to convince your computer to boot from our USB drive or DVD instead of its usual routine. Think of it like telling your stomach to crave pizza instead of broccoli (much easier, I know!). This involves diving into the BIOS/UEFI settings, which sounds scarier than it is. Trust me, it’s like navigating a slightly outdated menu – we’ll get through it together.

Entering BIOS/UEFI: The Gateway to Boot Options

Okay, so how do we get into this mysterious BIOS/UEFI realm? Well, it’s all about timing and pressing the right key at the right moment. As your HP laptop starts up, there’s usually a tiny window of opportunity to press a specific key that grants you access. Common keys to try on HP Laptop Models are Esc, F10, F2, and sometimes F12. It’s almost like a secret handshake!

Keep an eye on the screen during startup – it often flashes a message indicating which key to press, so pay attention!. If you miss the prompt, don’t sweat it! Just restart your laptop and try again. Persistence is key, my friend!

Once you’re in the BIOS/UEFI setup, you might see a screen that looks like it’s straight out of a 90’s sci-fi movie. Don’t panic! We are looking for the Boot Menu or the Boot Options. Use your arrow keys to navigate to the right tab (often labeled “Boot,” “Boot Order,” or something similar).

Configuring Boot Order: Prioritizing the Installation Media

Now, the main goal here is to tell your laptop, “Hey, ignore the usual startup routine and boot from this USB/DVD drive instead!”. This means we need to change the Boot Order. This usually involves highlighting your USB drive or DVD drive and moving it to the top of the list using the arrow keys or the + and – keys. Make sure the installation media is at the very top and will be loaded first.

You might also encounter something called Secure Boot. This is a security feature designed to prevent malicious software from loading during startup. Sometimes, Secure Boot can interfere with booting from external media. In this case, you might need to disable Secure Boot temporarily. However, be aware that disabling Secure Boot can potentially make your system more vulnerable to certain types of malware. If you choose to disable it, make sure to re-enable it after you’ve finished reinstalling Windows.

Understanding CSM (Compatibility Support Module): Legacy Support

Finally, let’s talk about CSM (Compatibility Support Module). This is a setting that allows your laptop to support older operating systems and hardware. You’ll most likely not need this these days. For the most part modern systems won’t need this enabled, but in some cases, enabling CSM might be necessary if you’re installing an older version of Windows or if you’re using some legacy hardware. If you’re unsure, leave it disabled, but if you’re having trouble booting from your installation media, try enabling CSM to see if that resolves the issue.

Initiating Windows Installation: The Clean Slate Approach

Alright, buckle up! You’ve prepped your HP laptop, backed up your precious data, and tweaked the BIOS settings. Now, it’s time for the main event: installing Windows! Think of this as giving your laptop a digital bath – scrubbing away all the grime and starting fresh.

Booting from the Installation Media: Starting the Process

First things first, you need to tell your laptop to boot from that USB drive or DVD you so diligently created. Remember that boot menu we accessed in the BIOS/UEFI settings? It’s time to revisit it.

Restart your HP laptop.
As it’s booting up, repeatedly press the designated key (usually Esc, F10, F2, or F9 – keep an eye on the screen for the prompt!) to access the boot menu.
Using the arrow keys, navigate to your USB drive or DVD drive (it might be listed under “Removable Devices” or something similar).
Press Enter to select it.

If all goes well, you should see the Windows logo appear, indicating that the installation process has begun. But, what if your computer stubbornly refuses to boot from the media? Don’t panic! Here are a few things to try:

Double-check the boot order: Make sure the USB drive/DVD drive is actually at the top of the boot order in the BIOS/UEFI settings.
Ensure the USB drive is bootable: Verify that you created the bootable USB drive correctly using the Media Creation Tool. Try recreating it if you’re unsure.
Disable Secure Boot: Some systems require you to disable Secure Boot in the BIOS/UEFI settings before they’ll boot from external media. Remember to note your settings before changing them!
Try a different USB port: Sometimes, certain USB ports can be finicky. Try plugging the USB drive into a different port on your laptop.

Clean Install vs. In-Place Upgrade: Choosing the Right Path

Now, you’ll be presented with a choice: a Clean Install or an In-Place Upgrade. For our purposes (and for the absolute best results), we’re going for the Clean Install.

Think of an In-Place Upgrade as just sweeping the dirt under the rug. While it might seem easier, it can carry over old problems, corrupted files, and other digital gunk. A Clean Install, on the other hand, is like demolishing the old house and building a brand-new one on the same lot. It wipes everything clean and installs a fresh copy of Windows, resulting in improved performance, stability, and overall happiness for your laptop.

Partitioning the Hard Drive/SSD: Allocating Space for Windows

This is where things can get a little intimidating, but don’t worry, we’ll take it slow. The partitioning step involves dividing your hard drive or SSD into sections for Windows to use. During a clean install, you’ll typically want to delete any existing partitions to start with a truly blank slate.

Warning: Deleting partitions will erase all data on those partitions. Make absolutely sure you have backed up everything important before proceeding!

Here’s how it usually goes:

You’ll see a list of existing partitions. Select each one and click “Delete”. Yes, even the ones that say “Recovery” or “System Reserved” (you did create a backup, right?).
Once you’ve deleted all the partitions, you’ll have a single, large block of unallocated space.
Select the unallocated space and click “New”. Windows will usually suggest a size for the primary partition (where Windows itself will be installed). You can accept the default size or specify a different size if you want to create multiple partitions.
Click “Apply”. Windows might create a few additional partitions automatically (like a system partition). That’s perfectly normal.
Select the primary partition you just created (the one with the most space) and click “Next” to install Windows on that partition.

File System: Selecting the Right Format

You’ll likely be prompted to choose a file system for your partition. The standard and recommended file system for Windows is NTFS (New Technology File System). Unless you have a specific reason to choose otherwise, stick with NTFS. It’s the most compatible and reliable option for modern Windows installations.

Understanding GPT (GUID Partition Table) and MBR (Master Boot Record): Partition Schemes

Finally, let’s touch on GPT and MBR, which are partition schemes. Think of them as different ways of organizing the data on your hard drive.

GPT (GUID Partition Table) is the modern standard. It’s more robust, supports larger hard drives, and is generally preferred for newer systems.
MBR (Master Boot Record) is an older standard. It has limitations in terms of drive size and the number of partitions it can support.

In most cases, you’ll want to choose GPT if your system supports it. The Windows installation process will usually handle this automatically. If you are using an older computer that doesn’t support UEFI, it might require you to use MBR. If you see options related to converting to GPT or MBR during the partitioning process, generally opt for GPT if you have a modern system.

Take a deep breath; you’re through the most technically demanding part! Now, you can sit back and let Windows install itself onto your squeaky-clean hard drive. The next step involves following the on-screen prompts to personalize your installation.

Completing Windows Setup: It’s Almost Showtime!

Alright, you’ve navigated the tricky bits – booting from your USB, wrestling with partitions (hopefully without losing any data!). Now, it’s time for the home stretch: completing the Windows setup. This is where you get to personalize your shiny, new operating system and make it yours. Think of it as the final coat of paint on your freshly renovated HP laptop!

Following the On-Screen Prompts: Easy Does It

The installation wizard is designed to be user-friendly, so just take your time and read each screen carefully. First up, you’ll be prompted to select your language, region, and keyboard layout. Choose the options that best suit you. Don’t worry, these aren’t set in stone! You can always change them later in the Windows settings if you suddenly decide you’d rather type in Klingon.

Next up is the moment of truth: entering your Product Key. Hopefully, you followed our earlier advice and have this handy! Type it in carefully (double-check for typos!). This key is what activates your Windows copy and proves you’re a legitimate user. No key, no candy… well, no activated Windows, anyway. If you can’t find your key, there’s often an option to skip this step (temporarily), but remember, you’ll need to activate Windows eventually to enjoy all its features!

Creating an Account: To Microsoft, or Not to Microsoft?

Now comes a pivotal decision: Microsoft Account or Local Account? Let’s break it down:

Microsoft Account: This ties your Windows login to your Microsoft account (Outlook, Xbox, etc.). The upside is seamless syncing of settings and files across devices, easy access to Microsoft services, and the ability to download apps from the Microsoft Store. The downside is that you need an internet connection to log in initially, and some people are wary of having their data tied to a Microsoft account (privacy concerns).
Local Account: This is a traditional account that lives solely on your laptop. The upside is increased privacy (your data stays on your device) and no need for an internet connection to log in. The downside is that you miss out on the syncing and integration benefits of a Microsoft account.

Which should you choose? It depends on your personal preference. If you’re heavily invested in the Microsoft ecosystem, a Microsoft account is a no-brainer. If you value privacy and simplicity, a local account might be a better fit.

Configuring Privacy Settings: Your Data, Your Rules

Windows will present you with several privacy settings screens. Pay close attention! These settings control how much data Windows collects about you and how it’s used. Read each option carefully and choose the settings that align with your comfort level. There’s no right or wrong answer here; it’s all about finding the balance between convenience and privacy that works for you. You can always adjust these settings later in the Windows settings app.

Post-Installation Tasks: Leveling Up Your Freshly Installed System

Alright, you’ve braved the Windows reinstallation process and emerged victorious! Give yourself a pat on the back! But hold on, the journey isn’t quite over yet. Think of this as the post-game show – the tasks you perform now will determine how smoothly your HP laptop runs moving forward. We’re talking about giving your system a proper tune-up to unleash its full potential. Let’s dive into the essential post-installation tasks, which include installing the proper drivers, keeping Windows updated, and getting your precious data back where it belongs.

Installing Drivers: Making Sure Everything Talks to Each Other

Imagine throwing a party where none of your guests can understand each other. Total chaos, right? That’s what it’s like when your hardware doesn’t have the right drivers. Drivers are the little translators that allow your operating system to communicate with all the cool gadgets inside your HP laptop – the graphics card, the sound card, the Wi-Fi adapter, everything!

Skipping this step is like trying to drive a car with square wheels. It might work (sort of), but it won’t be pretty, or efficient. You absolutely need the latest drivers to ensure optimal performance and prevent random crashes or glitches. So, how do you get these magical translators?

HP Support Assistant to the Rescue:
Think of the HP Support Assistant as your personal tech concierge. This handy tool often comes pre-installed on HP laptops, and it’s designed to automatically identify and install the latest drivers for your specific model. Just fire it up, let it scan your system, and follow the prompts. It’s usually the easiest and safest route.
The Official HP Website: A Treasure Trove of Drivers:
If the HP Support Assistant isn’t cutting it, head straight to the source: HP’s official website. Navigate to the support section, enter your laptop’s model number (remember when we identified that earlier?), and download the drivers manually. This is the best option if you want the absolute newest version, or if you’re having trouble with the Support Assistant. Be sure to grab the drivers directly from HP, as they’re tailored for your machine and have passed testing. This will ensure that your Windows runs efficiently and smoothly.

Updating Windows: Keeping Your Castle Safe and Sound

Now that your drivers are sorted, it’s time to fortify your system by installing all available Windows updates. Think of these updates as digital armor, protecting your laptop from viruses, malware, and other online nasties. Plus, they often include performance improvements and new features that can make your life easier.

To check for updates, simply type “Windows Update” in the search bar and click “Check for updates.” Windows will then scan for any available updates and prompt you to install them. It’s like giving your laptop a regular checkup to keep it running in tip-top shape. This can be done by:

Clicking the Windows “Start” button
Clicking the “Settings” icon (looks like a gear or cog)
Clicking “Update & Security”
Finally, click on “Check for Updates”

Restoring Data: Welcome Home, Files!

Remember that backup we made before nuking your system? Now it’s time to bring those files back home where they belong! Connect your external hard drive or log in to your cloud storage service and carefully copy your precious documents, photos, videos, and other data back onto your newly cleaned and optimized HP laptop. Drag, drop, and celebrate!

Hard Drive/SSD Transfers:
For local backups from your hard drive, simply drag the files from your backup source into the newly created folders on the Hard Drive/SSD.
Cloud Storage:
When pulling the files down from the cloud, be sure to organize the files as you did beforehand. This will make for a much easier time finding and working with them.

Restoring your data can take some time, depending on how much you have, but the feeling of having all your stuff back is oh-so-sweet! You’ve now breathed new life into your HP laptop with a clean Windows install, up-to-date drivers, all the latest system security and feature updates, and all the data you love and need.

Troubleshooting Common Issues: Overcoming Installation Hurdles

Alright, so you’re almost there! You’ve battled through BIOS, conquered partitions, and are staring at the beautiful blank canvas of a fresh Windows install. But what if…dun dun DUN… something goes wrong? Don’t panic! Everyone hits a snag sometimes. Let’s troubleshoot some of the common gremlins that might pop up and how to banish them back to the digital shadows.

Installation Errors: When the Process Grinds to a Halt:
- “Windows could not be installed to this disk”: This cryptic message often points to partition issues or incorrect boot settings. Double-check your BIOS/UEFI settings and ensure the drive is formatted correctly (NTFS).
- Installation gets stuck at a certain percentage: Patience, young Padawan! Sometimes, it just takes a while. But if it’s been hours and the progress bar hasn’t budged, try restarting the process. If the issue persists, your installation media might be corrupted.
- Missing DLL files or other error codes: Jot down the error code! A quick Google search will often lead you to specific solutions. It could be a corrupted installation file, a driver conflict, or even a RAM issue.
Driver Drama: When Your Hardware Refuses to Cooperate:
- No Wi-Fi after installation: A classic! Windows often doesn’t have the drivers for your Wi-Fi adapter right away. Use a wired Ethernet connection (if possible) to get online and let Windows Update find the drivers. Alternatively, download the drivers from HP’s website using another computer and transfer them via USB.
- Display issues (low resolution, glitches): Your graphics drivers are probably missing or outdated. Download the latest drivers from HP’s website or the manufacturer’s website (Nvidia, AMD, Intel).
- Other hardware not working (sound, webcam, etc.): Same drill! Head to HP’s website, find your specific laptop model, and download the drivers for the offending hardware.
General Troubleshooting Tips
- ***Restart***: Seriously, sometimes a simple restart is all it takes to shake off a temporary glitch.
- Check your hardware: Run diagnostics on your HDD/SSD or RAM if you suspect an issue. If you can get into BIOS/UEFI you could find the testing tool under the utility setting.
- ***Ensure your BIOS/UEFI are set up correctly***: Sometimes a simple reset can solve the problems.

Remember, the internet is your friend! Don’t be afraid to search for specific error messages or problems you’re encountering. Chances are, someone else has already faced the same issue and found a solution. Good luck, and happy computing!

HP-Specific Recovery Options: Unleashing HP’s Secret Weapons!

So, you’ve got an HP laptop, and things have gone south? Don’t panic! Before you dive headfirst into a full Windows reinstall, let’s explore some HP-exclusive recovery options. Think of these as your laptop’s built-in superpowers for bouncing back from trouble. We’re talking about the Recovery Partition, the trusty HP Recovery Manager, and the modern marvel of Cloud Recovery. They’re all designed to save you time, effort, and maybe even a few grey hairs. Let’s check these out!

Using the Recovery Partition: Your Laptop’s Time Machine

Imagine your laptop had a secret time machine that could whisk it back to the day it left the factory. That’s essentially what the Recovery Partition does. It’s a hidden section of your hard drive containing a pristine image of your original Windows installation, complete with all the drivers and software HP pre-installed.

So, how do you access this magical realm? Well, the exact steps can vary slightly depending on your HP model, but the general idea is this:

Restart your laptop: Simple enough, right?
Press the magic key: As your laptop boots up, start tapping a specific key. This is usually Esc, F11, or sometimes F10. You might need to consult your laptop’s manual (or a quick Google search) to be absolutely sure.
Navigate the Recovery Menu: With a bit of luck, you’ll enter a special recovery menu. From there, look for an option like “System Recovery,” “Factory Reset,” or something similar. Follow the on-screen prompts, and your laptop will begin the journey back in time.

Important Note: This will wipe out any data you’ve added since you first bought your laptop. That’s why backing up your data (as we discussed earlier) is absolutely essential before attempting a recovery.

HP Recovery Manager: Your Friendly Neighborhood Recovery Tool

Think of HP Recovery Manager as a dedicated app designed to help you recover your system. It’s like having a friendly IT technician built right into your HP machine. It’s typically pre-installed on your HP laptop and offers a user-friendly interface for performing various recovery tasks.

Finding and Launching It: Usually, you can find it by searching in the Windows search bar. Just type “HP Recovery Manager”.
Using the tool: Once opened, it will guide you through options like performing a system restore, creating recovery media (like a USB drive), and more.

Cloud Recovery: Downloading Windows from the Heavens (Well, HP’s Servers)

If your Recovery Partition is missing or corrupted (yikes!), or if you just want the latest version of Windows, Cloud Recovery might be your best bet. This feature allows you to download a fresh copy of Windows directly from HP’s servers and reinstall it on your laptop.

Here’s the catch: you’ll need a stable internet connection for this to work. Think of it as downloading a massive file – a shaky connection could lead to a frustratingly interrupted process.

How to Access Cloud Recovery: It varies slightly depending on your model but often involves starting the computer, pressing the Esc key repeatedly, then going into the F11 system recovery options.
Follow the on-screen prompts: The tool will guide you through connecting to your network and downloading the necessary files to reinstall windows.

And that’s a wrap on HP’s built-in recovery tools! Hopefully, one of these options will get your HP laptop back on its feet without the need for a full Windows reinstallation. Fingers crossed!

Advanced Tasks (Optional): For the Tech-Savvy Ninjas

Alright, so you’ve made it this far! You’re feeling pretty good about yourself, right? You should be! But now, we’re entering the realm of tech wizardry. This section is for those of you who like to live on the edge, the folks who aren’t afraid to get their hands dirty with a little command-line action. If you’re not super comfortable with computers, maybe grab a cup of coffee and skip ahead. No judgement here! But if you’re ready to level up, let’s dive in!

Using Command Prompt (Diskpart): Advanced Partitioning

Okay, here’s the deal: Command Prompt, especially when combined with Diskpart, is like a surgical tool for your hard drive. It’s incredibly powerful, but with great power comes great responsibility. Messing around with the wrong commands can lead to some serious data loss, like “Oops, I just accidentally wiped everything!” So, seriously, proceed with caution and back up your stuff!

First things first: Open Command Prompt as an administrator. You can do this by searching for “cmd” in the Windows search bar, right-clicking on “Command Prompt,” and selecting “Run as administrator.” Make sure you do this, or things won’t work!
Type “diskpart” and press Enter. This launches the Diskpart utility. You should see a new DISKPART> prompt.
List Disks: Type list disk and press Enter. This shows you all the disks connected to your computer. Identify the correct disk number you want to work with.
Important: Be absolutely sure you select the correct disk. Double, triple, quadruple check!
Select Disk: Type select disk [disk number] (replace [disk number] with the actual number of the disk). For example, select disk 0. Press Enter.
Clean (Use With Extreme Caution): Type clean and press Enter. THIS WILL ERASE ALL PARTITIONS AND DATA ON THE SELECTED DISK! I’m serious, this is your last warning! This essentially sets the disk back to a completely unallocated state.
Create Partition Primary: To create a new partition, type create partition primary size=[size in MB]. Replace [size in MB] with the size you want the partition to be in megabytes. For example, create partition primary size=50000 would create a 50GB partition.
Select Partition: Type select partition [partition number] to select the partition you just created (usually partition 1).
Format Partition: Type format fs=ntfs quick. This formats the selected partition with the NTFS file system quickly.
Assign a Letter: Type assign letter=[drive letter] to assign a drive letter to the partition (e.g., assign letter=E).
Exit Diskpart: Type exit to exit Diskpart. Then type exit again to close the Command Prompt.

Remember: This is just a brief overview. Diskpart has tons of other options, like creating extended partitions, logical drives, and more. But for the purposes of a clean Windows install, this is the gist. Again, be careful, and don’t blame me if you accidentally delete your cat pictures! Use this knowledge wisely, young padawans!

And that’s pretty much it! Reinstalling Windows from the boot menu might seem daunting, but with a little patience, you can get your HP laptop back to its fresh-out-of-the-box glory. Hope this helps you breathe new life into your machine!
