I don't know how to get the bios/firmware menu.
I need to change it to legacy and boot from the flash drive.
Trying to replace win7 with ubuntu which I've downloaded and extracted onto my usb.
I know how to get the boot menu but that doesn't have the options I need only which version of windows 7 I want to boot, even advanced menu doesn't list what I want.
Have searched everywhere, does anyone know how to get the bios menu?
