Because Win 8 boots so fast, it is easy to miss the key press window. You need to bypass Fast Boot. Do a Restart from within Windows by pressing and holding the Shift key before pressing Restart. You will then have more time to press F2.
I can't access BIOS. I have an XPS One 2710 ( mid 2012) operating Windows 8.1 with Dell BIOS v A09. When the Dell Logo appears on screen at boot up, pressing F2 or F12 doesn't access BIOS. When the Dell Logo appears on screen, press F2 or F12 does not display. Any suggestions?
