For booting Windows after you installed linuxbios.
You still aren't makeing sense to me. Booting a COTS bios after you boot linuxbios to boot windows is a regression not an advancement. You aren't getting any extra features. You are just adding complexity. If you are going to boot a COTS bios then just boot the COTS bios you don't need linuxbios.
-- Richard A. Smith
It makes sense if you usually want to boot Linux, but sometimes want to boot Windows.
