Multiboot Qubes with GRUB on a different drive

User Support

Did you install Qubes with a boot partition? If so, could you try this:

When GRUB loads you normal menu, press ‘c’ and type:

configfile (hdX,gptY)/efi/qubes/grub.cfg

? - If you don’t know X and Y, you should be able to press tab and get a list of known partitions – look for “Filesystem type fat”. If this works, I think you can do something like:

I’ve not tested it, but looks like you should be able to add something like:

menuentry "Give me QUBES" {
   insmod xfs
   search --set=root --label OS1 --hint hdX,gptY
   configfile /efi/qubes/grub.cfg
}

to your normal GRUB configuration.
