How to recover Grub after a Windows installation

05 Jul 2017 / ERap320

In an administrative Windows' cmd prompt:

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

If the Linux distribution isn't Ubuntu you can just swap the name of the directory.

If you don't know the exact name of the directory find a way of mounting the EFI partition (it's just FAT32) and check what's in there.
