Image generation breaks on UEFI systems #3

Closed arthurmco closed 8 years ago

arthurmco commented 8 years ago

Since we depend on i386 GRUB to generate our ISO, we can't make an ISO image on UEFI, since GRUB generates an UEFI image in these systems, whose it's incompatible with BIOS computers

Solutions are

UEFI compatibility?
write our own bootloader?

If you compile BIOS-made GRUB and modify makefiles to point to that, it seems to work. However, I need something working out-of-the-box. Download and compile grub-pc?

Fixed with grub-pc. It generates an EFI-MBR hybrid bootable disk, which is sad, because RainOS doesn't support a framebuffer in the main branch. Need to update multiboot-vbe
