First, thank you Pavroo for help with the logon problem, hope you get that fixed soon. Second: work has just got new pcs, and whenever I try to boot from my usb or live install, all I get is a screen saying press f11 to enter recovery and a countdown timer, after which windows boots.(to be precise, f9 for boot menu, select usb, get f11 for recovery, then windows).
Is there something I need to do in bios to fix this? Or am I doing something wrong?
