Unable to install

I’m left with the feeling that SeaBIOS is the problem. Can anyone help me put in grub as the coreboot payload and skip BIOS altogether?

I’ve verified that grub is installed on the disk and the boot partition is boot-able.

  • fdisk -l shows that sda1 is bootable
  • file -s /dev/sda shows me there’s an mbr
  • file -s /dev/sda1 shows me the UUID, which is present in /boot/grub/grub.cfg
  • dd bs=512 count=1 if=/dev/sda 2>/dev/null | strings|grep GRUB turns up the string GRUB
