IIUC, the GRUB menu is not even displayed. However you may be correct about a graphics mode issue, but in GRUB, not the kernel. I have seen it on a couple of machines/graphic cards. Boot the system on the other machine or chroot from the installer or any live system. Edit /etc/default/grub to uncomment GRUB_TERMINAL=console. Run update-grub to regenerate the grub config file. Try to boot again on the single board.
