bcdedit /set {bootmgr} path \efi\ubuntu\grubx64.efi
bcdedit /set {bootmgr} path \efi\ubuntu\grubx64.efi - {bootmgr}: This targets the Windows Boot Manager.
- path \efi\ubuntu\grubx64.efi: This tells the Windows Boot Manager that instead of looking for the Windows startup file, it should point directly to the GRUB bootloader file located on your EFI partition. - Boot into Windows: Since GRUB is missing, you’re likely already here.
- Open CMD as Admin: Press the Win key, type cmd, right-click it, and select Run as Administrator. This is crucial; the command will fail without elevated permissions.
- Run the Command: Copy and paste the command above and hit Enter. You should see a message saying "The operation completed successfully."
- Restart: Reboot your machine. Your GRUB menu should reappear, giving you back access to your Linux world. - Secure Boot: Sometimes Secure Boot prevents the handoff to GRUB. Try disabling it in your BIOS/UEFI settings if the problem persists.
- Path Variation: If you aren't using Ubuntu, the folder name might be different. For example, Fedora users would likely use \efi\fedora\grubx64.efi.
