I usually press DEL or F2 but if I do that it doesn't go into BIOS but it stays blank (black screen) then seems like frozen there whatever I would try. If I restart the computer and don't press any keys then it goes into debian jessie and loads the Linux fine.
I know it sounds like not a Linux problem but it only happened to me now with the Debian jessie and never before.
did you try esc key, google your make and model with key words access BIOS key to access BIOS and such things as that yet?
when you do find it press and hold it as soon as you just turn on the pc
