How to Remove GNU GRUB and Restore Windows Bootloader After Uninstalling PrimeOS

After uninstalling PrimeOS, it's common for systems to face issues where the GNU GRUB bootloader pops up, forcing you to choose between PrimeOS or Windows during startup. Restoring the Windows bootloader can resolve this problem. Here’s a comprehensive guide on how to achieve this using various methods.

Common Issue: GRUB Boots Windows

When you uninstall PrimeOS, the GRUB bootloader may not recognize the absence of PrimeOS, leading to a situation where the system lists both PrimeOS and Windows during boot time. This can be frustrating if you no longer use PrimeOS and wish to boot directly into Windows.

Solution: Restore the Windows Bootloader

To rectify this issue and ensure a seamless boot directly into Windows, you need to restore the Windows bootloader. Here’s a step-by-step guide to accomplish this using different methods:

Method 1: Using Windows Installation Media

Create Windows Installation Media: If you don’t have a Windows installation disc or USB, you can create one using the Windows Media Creation Tool.

Booting from the Installation Media: Insert the USB or DVD and restart your computer. You may need to change the boot order in the BIOS/UEFI settings to boot from the installation media.

Access Repair Options: When the Windows Setup screen appears, select your language preferences and click Next. Then, click on Repair your computer in the lower-left corner.

Navigate to Command Prompt: Select Troubleshoot rarr; Advanced options rarr; Command Prompt.

Restore the Windows Bootloader: In the Command Prompt, type the following commands one by one, pressing Enter after each command:

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

Exit and Restart: Type exit to close the Command Prompt, then select Continue to boot into Windows.

Method 2: Using a Windows Recovery Drive

If you have a Windows recovery drive, the steps are similar:

Boot from the recovery drive. Select Repair your computer rarr; Troubleshoot rarr; Advanced options rarr; Command Prompt. Run the same bootrec commands listed above. Exit and restart your computer.

Method 3: Using Third-Party Tools

If the above methods do not work, you can also consider using third-party tools like EasyBCD or Visual BCD Editor. These tools can help you manage and modify the bootloader settings, ensuring a smooth boot process.

Conclusion

After successfully following these steps, your computer should boot directly into Windows without displaying the GRUB menu. If you encounter any issues during the process, feel free to ask for further assistance!
