If you’ve been struggling to access your computer and need to reinstall Windows without losing any of your important files, you’re in the right place. In this guide, I’ll walk you through the entire process of reinstalling Windows on a drive that already has Windows installed, even if you can’t access the system anymore. These steps are easy to follow, whether you have access to your PC or not.
Key Takeaways
- Reinstall Windows without deleting personal files.
- Determine if your drive is formatted as GPT or MBR before reinstalling.
- Use the correct boot mode (UEFI or Legacy) based on your drive’s format.
Requirements
- USB flash drive with Windows installation media (created with Ventoy or other tools).
- Basic understanding of accessing BIOS/boot menu.
- Internet connection (for downloading the latest Windows version, if needed).
Step 1: Open Command Prompt in Windows Recovery
If your computer won’t boot into Windows, the first step is to access the command prompt from the advanced options.
- Restart your computer and boot into Windows recovery by selecting Troubleshoot and then Advanced options.
- Select Command Prompt from the menu.
Step 2: Use DiskPart to Check Disk Format
Next, determine whether your drive is formatted as GPT or MBR, as this will influence the boot mode you’ll need to select.
- Type
diskpartand press Enter. - Type
list diskand press Enter. - Look at the GPT column. If there is an asterisk, the disk is GPT; if not, it’s MBR.
Step 3: Boot from Windows Installation Media
Now, create a bootable USB flash drive with the Windows installation ISO file if you haven’t already. I recommend using the Ventoy tool for this process, which allows you to easily boot from a variety of ISO files.
- Download and install Ventoy on your USB flash drive.
- Copy the Windows ISO file (Windows 10 or Windows 11 depending on the version you want to install) onto the USB drive.
- Restart your computer and boot from the USB flash drive.
For detailed instructions, check out my guide on How to Create a USB Rescue Disk with Ventoy: A Step-by-Step Guide.
Step 4: Select the Correct Boot Mode
This is a critical step, as choosing the wrong boot mode can prevent the reinstallation process from working properly. Depending on how your hard drive is formatted (GPT or MBR), you’ll need to select the appropriate boot mode in your computer’s BIOS settings. Let me walk you through how to access the BIOS and configure the boot mode for either Legacy or UEFI.
Restart Your Computer:
As soon as the system starts rebooting, press the BIOS access key for your machine. This key is typically one of the following: F2, Delete, Esc, or F12, but it can vary based on the manufacturer. You should see a prompt during the boot process that says something like “Press [Key] to enter Setup.”
Access the BIOS Settings:
Once inside the BIOS, use the arrow keys to navigate through the menus. Look for an option labeled Boot or Boot Menu, as this is where you will configure the boot options.
Enable Legacy/UEFI Boot Mode:
If your system is GPT-formatted, look for the UEFI boot option. Navigate to the Boot Mode or CSM (Compatibility Support Module) section in the BIOS.
If your system is MBR-formatted, you need to enable the Legacy BIOS boot mode or CSM support. In this section, change the Boot Mode Selection to Legacy or CSM (depending on your BIOS manufacturer).
Save Changes and Exit:
After selecting the appropriate boot mode, navigate to the Save and Exit option. The exact wording might differ depending on your BIOS version, but it is often labeled something like Save & Exit Setup or Exit Saving Changes. Select this option and press Enter. Your computer will then restart, and you should now see the correct boot options in the boot menu.
Select the Correct Boot Option:
During the reboot, press the Boot Menu key (often F12 or similar) to bring up the boot options menu. Here, you should see your USB flash drive listed twice—once under UEFI and once under Legacy BIOS. Select the boot mode that corresponds to your drive format (UEFI for GPT, Legacy for MBR).
By ensuring you choose the correct boot mode, you’ll avoid compatibility issues and ensure the Windows installation process goes smoothly.
Step 5: Install Windows Without Deleting Files
Once you’ve booted from the installation media, follow the Windows setup steps.
- Choose your region and language settings.
- Click Install Now and select I don’t have a product key (if necessary).
- Choose the version of Windows you want to install (Windows 10 Pro or similar).
- Select Custom: Install Windows Only.
- Choose the partition where Windows is currently installed.
If you see a message indicating that the selected disk is of the GPT or MBR partition style, restart your computer and choose the correct boot mode.

Step 6: Recover Your Data from Windows.old Folder
After completing the Windows reinstallation, your previous Windows files, settings, and personal data will be moved to a folder called Windows.old on your system’s C: drive. This folder contains everything from your old installation, including desktop files, documents, and downloads, and can be a lifesaver if you forgot to back up any important files beforehand. Follow these steps to recover your data:
Open File Explorer:
Start by opening File Explorer from the taskbar or by pressing Windows Key + E on your keyboard.
Navigate to C:\Windows.old:
In the left-hand sidebar of File Explorer, click on This PC, then double-click on the Local Disk (C:) drive. Once inside, you’ll see a folder named Windows.old. Double-click on it to access its contents.
Find Your Old User Account:
Inside the Windows.old folder, open the Users directory. This will contain folders representing all user accounts that were present on the old installation of Windows. Open the folder corresponding to your old user account.
Recover Your Files:
You’ll now see familiar folders like Desktop, Documents, Downloads, and more. To recover your files, simply navigate to each folder, select the files you want to restore, and copy them to the corresponding location in your new user profile. You can drag and drop the files or use Ctrl + C to copy and Ctrl + V to paste them into your new Windows installation folders.
Example:
- Navigate to Desktop if you want to recover files that were saved on your old desktop.
- Similarly, go to Documents or Downloads for personal files stored there.
Open Two Explorer Windows for Faster Copying:
To make it easier to copy your files, you can open a second File Explorer window by holding Shift and clicking on the File Explorer icon again. Position the two windows side by side—one showing the Windows.old folder and the other showing your new user profile in C:\Users. Then, drag the files from the old profile to the new one.
Ensure All Files are Recovered:
Go through all of the folders (Desktop, Documents, Downloads, etc.) to ensure you’ve recovered all the important files from the Windows.old folder. Once you’ve copied everything over to your new user profile, double-check that nothing essential has been left behind.
By following these steps, you can successfully restore your important files from your old Windows installation. Just be sure to check thoroughly so that no important data is missed before cleaning up your system.
Step 7: Clean Up Your System
After recovering your files, you can safely remove the Windows.old folder to free up space.
- Right-click on C: drive and select Properties.
- Click Disk Cleanup and select Clean up system files.
- Check the box for Previous Windows Installations and click OK.
Conclusion
Reinstalling Windows without losing your files may seem intimidating, but following these steps ensures that your data remains intact while you get a fresh installation of Windows. Be sure to check your disk format and use the correct boot mode to avoid issues.

Common issues and troubleshooting tips during reinstallation
While reinstalling Windows 10 is usually straightforward, users may occasionally encounter issues that disrupt the process. Here are some common problems and troubleshooting steps to ensure a smooth reinstallation:
- Stuck on Loading Screen: If the installation process seems stuck on a loading screen, give it time — sometimes it takes longer than expected. If it remains unresponsive for over an hour, try restarting the computer and initiating the installation again. Ensure your device is connected to a stable power source to prevent accidental shutdowns.
- Error Codes: Windows 10 may display error codes if issues arise during reinstallation. Common codes like 0xC1900101 indicate driver-related problems. Try updating your device drivers before reinstalling or disconnecting unnecessary peripherals to avoid conflicts.
- Internet Connection Failures: A slow or interrupted internet connection can hinder the installation, especially if you’re using the Windows Update method. To avoid this, consider using an Ethernet connection or download the ISO file directly to use offline.
- Insufficient Disk Space: If you receive a notification about limited storage, free up space by moving non-essential files to an external drive or cloud storage. Windows 10 reinstallation generally requires at least 20GB of free space.
- Reinstallation Loop: Occasionally, users find their system caught in a reinstallation loop, where it repeatedly tries to reinstall. In this case, boot into Safe Mode and use the “Reset this PC” feature again, ensuring you select the correct reinstallation option.

While freezes or errors during reinstallation are uncommon, they can occasionally occur. If the update animation is still moving, it’s usually a sign that the process is working as intended.
