To fix GRUB installation issues alongside Windows 11, the most common solution is to boot your Linux installer into UEFI mode rather than Legacy/CSM. Windows 11 relies on UEFI and requires your Linux bootloader to use the same mode, along with an active EFI partition.

Follow these steps to restore GRUB:
  1. Verify your Boot Mode: Restart your computer, enter your motherboard's UEFI/BIOS settings, and ensure Secure Boot is temporarily disabled and UEFI mode is enabled.

  2. Boot the Live USB: Create a bootable Linux USB using tools like https://rufus.ie/.." ping="/url?sa=t&source=web&rct=j&url=https://rufus.ie/&ved=2ahUKEwi6xPayipyVAxUC-AI.." data-copy-service-computed-style="font-family: "Google Sans", Arial, sans-serif; font-size: 16px; font-weight: 500; margin: 0px; text-decoration: underline 1px rgb(26, 13, 171); border-bottom: 0px rgb(26, 13, 171);" style="margin: 0px; text-decoration-thickness: 1px; text-decoration-style: initial; text-decoration-color: rgb(26, 13, 171); border-bottom: 0px rgb(26, 13, 171);">⁠Rufus.

  3. Use Boot-Repair: Once booted into the live Linux environment, the easiest method is to install and run the Boot-Repair graphical tool. Open a terminal and run:
    sudo add-apt-repository ppa:yannubuntu/boot-repair
    sudo apt update
    sudo apt install boot-repair

  4. Apply Recommended Repair: Click "Recommended repair." This will automatically detect your OS, reinstall GRUB to your EFI system partition, and update the boot entries. [https://discourse.ubuntu.com/t/grub-not-working-pr..">1]
