I have a unique use case, I mainly produce music with Windows, use Qubes for school and development, and Gentoo for everything else. This facilitates the need for a tri-boot setup, with GRUB installed on a separate Gentoo SSD which has an entry for windows. The issue is that I have not found any documentation regarding adding an entry to successfully boot Qubes from GRUB on my Gentoo install. Could anyone point me in the right direction?
I should note that I am on Qubes 4.1.0 with a strictly UEFI bios configuration (no csm).
Yes it does show up, but that is what i’m trying to avoid. Entering the BIOS boot menu is really inconvenient and makes a super loud beep. I would like to boot qubes through my gentoo install, and the grub that sits on the /boot partition of that drive, if that makes sense
Yep i’ve using tried that and os-prober, and both try to launch dom0 without xen or something along those lines. It also has to load with special .efi files found in /boot. I’m not sure how to configure this without wrecking my other boot entries. I’ll do some testing when I get home later and see what works and what doesn’t.
Thank you so much! that did it. I just had to copy /efi/qubes over to the other /efi folder and add your custom entry. It’s definitely not pretty, since it loads grub again before booting, but functionality is perfect and I still have access to all of the recovery options.
