F8 didn't do anything.
I did notice, on my hopefull journey in, that F1 was Boot Menu and F10 was PC Recovery,if that's of any use...?
Oh,and Norton's finally fucked off for good. All traces erased. Yay! (There's £10 I'' never see again).
Still can't get access via a main link without it opening a new window with some random shitty video site in it though...
