Gateway, model GWTN156-78K
Also, and sorry to be obvious, but have you checked the laptop
manufacturer's website for BIOS documentation (often under Support)?
That should tell you what the magic key combo is to get to the BIOS
menu, which in turn will let you configure what boot device to use.
As reported earlier, I asked at the OEM's website over the weekend and
haven't received an answer. If I don't have a flash drive inserted at
boot, F12 gets me to BIOS. If I do, it goes right to the grub prompt
whatever I do. The hard drive is blank, so the only possible boot
device is that flash drive.
