Hi
I got a new Lenovo G580 laptop which did not come with any pre-installed OS. I installed Ubuntu in UEFI mode (I had not disabled UEFI/Secure Boot). Later I installed Windows 7. During installation it asked me to format the entire format as it did not recognize the GPT partition. Accordingly without thinking twice I erased the entire HDD and installed Windows 7. Now I am unable to enter into BIOS
Things I have tried:

Now I am unable to enter into BIOS
Things I have tried:
- Tried with F2, F1 and Delete keys while booting
- Tried removing the battery and booting while pressing the above keys individually
- Tried removing the battery and adapter, held the power button for 1 minute
- Tried removing the battery and held the power button for 1 minute while the adapter was plugged in
- Tried pressing F12 and going to the APP MENU but I can only see "Diagnostic Splash" Nothing else and in that diagnostic splash screen I see that the System BIOS is "shadowed"
