Can I remove Ubuntu and install Windows 10?

17 Answers. If you have a single-boot system with only Ubuntu installed, you can install Windows directly and override Ubuntu completely. To remove Ubuntu from a Ubuntu/Windows dual boot system, you will first need to replace the GRUB bootloader with the Windows bootloader.

Can I replace Ubuntu with Windows 10?

You can definitely have Windows 10 as your operating system. Since your previous operating system is not from Windows, you will need to purchase Windows 10 from a retail store and clean install it over Ubuntu.
