Alienware 17 - No Bios menus can't be accessed since A10v upgrade.

Hi guys. Alienware 17 just arrived, and it came with A05v bios so I decided to upgrade it. I've updated from A05v to A10v this morning since there's a big improvements upgrade jump, so I kept updating my system normally. Some minutes ago I decided to check the Bios menu out in order to verify and set my boot devices order. Once the system restarted, I pressed F2 on post state and I saw the red level fully filled but no menu was showed up. I've awaited for a couple of minutes hoping the menu could came up, but the screen was stuck. I reboot the system once more and I tried again pressing F12 getting same difference. I thought that something went wrong on A10 so I made a downgrade to A09 with same result. As a final workaround I decided to perform a downgrade to A05 with same difference again!. Although there's no way to get access to my Bios menu since it seems stuck, I have no issues accessing the OS at all ...so far. Has anybody experienced this issue before?. How can I get access to the Bios menu (F2) and Bios boot order devices (F12) once again?. Appreciated guys!.
