Can't acces BIOS!

(Don't know if this is the right section, if not, please move the thread)

Hi, I've had a Sony Vaio SVE14AA11M and it has been giving me a multitude of problems. I'll be creating other threads on other forums for the other problems, but this one regards a problem I'm having with the bios.

Basically, the issue I'm having is that I can't access it. I've tried pressing every function key,but there is no boot menu. This is a pain in the butt because I wanted to dual boot Windows 7 and Ubuntu to troubleshoot a few problems, but since there is no bios menu, I can't choose which operating system to load.

Holding down the F2 key during boot up is supposed to get you into bios.

I tried F9 and F12 and that did nothing. Aparently, F2 is the key you should prss, but the BIOS settings are VEEEERY limited, but I could at least change the boot mode from legacy to UEFI and now I can multi-boot, thanks.
