Can't access BIOS on W520

[pyrojoe]

After reading about how awesome UEFI is, when I did a clean install of Windows 7 on my W520, I set it to to be UEFI only. Things have been great, and my Thinkpad boots up faster than I could have hoped for, but there is one problem. I can no longer access my BIOS, or any related functions, such as selecting a boot device. This has been a pretty major inconvenience, as I cannot install another OS on any other partition.

Furthermore, I am worried that, if my computer crashes or become unable, I will be unable to recover it. I cannot boot from a CD drive or a USB drive at all. If I I try to and hold the blue ThinkVantage button down during bootup, it just boots straight to Windows.

Any help would be greatly appreciated.

Press f1 during boot will fix the problem

and F12 for boot options.

Just spam either F1 or F12 (depending on need) when you press power until it beeps at you.
