Which instance did you boot with rEFInd ? /dev/sdf is one of the SSD used for RAID 0 and LVM, right ? > root@mc:/boot/efi/EFI# apt-get install --reinstall grub-efi Note that grub-efi is a dummy package which depends on either grub-efi-amd64 or grub-efi-ia32 depending on the installed architecture. Reinstalling it does nothing. > root@mc:/boot/efi/EFI# grub-install /dev/sdf > Installing for x86_64-efi platform. > Installation finished. No error reported. The device name is not used by grub-install with an EFI target. You could have tried to use the option --boot-loader-id I mentionned in a previous post. > root@mc:/boot/efi/EFI# file /boot/efi/EFI/debian/grubx64.efi > /boot/efi/EFI/debian/grubx64.efi: PE32+ executable (EFI application) x86-64 > (stripped to external PDB), for MS Windows > root@mc:/boot/efi/EFI# efibootmgr --verbose | grep debian > Boot0000* debian > HD(1,GPT,87471e98-b814-4aa9-b2bc-ea4669c75565,0x800,0x100000)/File(\EFI\debian\grubx64.efi) Looks as expected. You can check with blkid which partition has PARTUUID=87471e98-b814-4aa9-b2bc-ea4669c75565. If you wonder about the formard / in the boot entry pathname, that's because the UEFI uses MS-style path. > A baffling point: In rEFInd the path is /boot/efi/EFI/debian/grubx64.efi How is it baffling ? The EFI system partition is mounted on /boot/efi and the path relative to the partition filesystem root is /EFI/debian/grubx64.efi. The EFI firmware does not care about where you mount the EFI system partition. > After booting up into the HDD instance, I get: Booting how ?
