I'm trying to boot Refind from the UEFI GRUB2, with the following commands, but I'm getting an error:

grub> chainloader (hd0)/refind_x64.efi /EndEntire file path: /ACPI(..../File(refind_x64.efi)/EndEntire grub> boot error: unknown error.

In fact, I get the same error when I try to boot the EFI shell version 2.

Somebody else got the same error message: https://tails.boum.org/contribute/design/UEFI/

The filesystem containing refind_x64.efi is ext2 directly on the device, there are no partitions.

How can I boot Refind from UEFI GRUB2?

  • Have you found a solution to this? I ran into the same problem while trying to boot Windows 10. Maybe set root=(hd0,Y); ($root)refind_x64.efi would work? (Can't test it right now.) – Arch Linux Tux Sep 12 '18 at 5:38
