How to Repair, Restore, or Reinstall Grub 2 with a Ubuntu Live CD or USB #28
Description
Hello, have become aware (after pointing a user to this repair information) that for a system using UEFI it is necessary to also add the line sudo mount /dev/sdXY /mnt/boot/efi where sdXY is the EFI partition.
Without this line, you will end up with errors along the lines of 'can't find EFI partition' and Grub won't install. Many systems now use UEFI, particularly when dual-booting, so would be pretty handy to make mention of that extra line to cover all use cases.
Apart from that, it's a very nice clear guide, hence directing someone else to it in the first place, but please make mention of this for UEFI use cases.
