I’m looking to add a custom Grub entry for the sake of multi-booting. Unfortunately, when I attempted to do this, the grub fails to update. I followed this: Qubes OS 3.2 - part 11 - qubes windows 7 multi/dual boot with grub - YouTube and had succeeded in updating grub2.cfg (in /boot/grub2/ originally, then to make sure /boot/efi/efi/qubes), but when I rebooted, nothing changed.
I’ve looked around for an answer to this issue but couldn’t find one. Any idea how to fix this?
