System doesn't boot on UEFI-only systems #6

Open James-Livesey opened 11 months ago

James-Livesey commented 11 months ago

x86-64 computers that run LiveG OS will boot the system in legacy mode instead of UEFI. We need to allow booting using UEFI by correctly building the ISO for the right GRUB version using grub-mkrescue.

Probably best to look at Debian's xorriso arguments to allow UEFI and BIOS booting: https://wiki.debian.org/RepackBootableISO#:~:text=equipment%20actually%20works.-,Learn%20about%20the%20actually%20used%20ISO%20production%20command,-The%20Debian%20installation
