Can not be used to restore a key

Users questions: I use the BenQ U101 small, would have been a key to restore, but then I do not know how, no boot prompt "Press F11 to restore your system", a key can not be restored. But Tip: Press ALT + F10 to enter Qtravedate. However, according to ALT + F10 nothing happens. Help you. Thank you.
