Sometimes, F8 doesn’t show up. As soon as the Toshiba splash screen shows up, hit F8 several times and it should bring up the boot menu. If there isn’t an initial splash screen, as soon as it starts to power up, press F8 several times. Eventually it’ll beep meaning the kbd buffer is full but that means the O/S will recognize the F8 and give you the boot option if the boot loader is still there.
Try that and then we’ll go from there.
f2 and f12 are the only options given.
f8 does not work(tried repeat tapping/holding)
