Could not acces Bios

Hello Everyone!

Please HELP!!!

I have An Acer aspire V5-571  with windows 8 preinstaled

I'll describe How I get in trouble:

First of all my problem was that I could not acces bios settings to set DVD unit to boot first. I did a lot of F2 pressing but nothing.

Finaly I've accesd bios through UEFI Advacend Settings:

 I've enabled F12 to apear during post.  I switched to legacy bios boot mode. I've set DVD to boot first. I've set a bios password to apear on boot.

(I did not now about: Secure Boot to disable it ; to enable compatibility mode ; to disable fast boot Smiley Sad((   )

 

I've saved settings.

After laptop restart, F2 and F12 option appeared during post but pressing them was again useless...

[THINK this is the reason (I did not now about: Secure Boot to disable it ; to enable compatibility mode ; to disable fast boot Smiley Sad((   )  ] ANYWAY

That did not bothered me because the DVD booted my Hirens's Boot CD

 

With Hirens Boot CD I've accesed the partition Tables. Paragon partition manager showed me that i have 2 disks:

As far as I can remember Disk 0 about 8 GB and Disk 1 (The 500Gb ) Hdd.

Disk 0 had 3 partitions FAT32

Disk 1 was a GPE partition compilation.

 

Not nowing the importance of FAT32 Partitions (EFI, Recovery) I've deleted them.

I also Changed the 500gb HDD from GPE to MBR ..

Then I've booted a Windows 7 DVD

After extracting files, more exactly after the first reboot that was part of W7 instalation setup , W7 freezed... I've tried 3 times and it was all the same...

I thoght it might be a compatibility issue. So I tried to again acces the bios.

Pressing f2 and f12 was again useless.

And because I've deleted the Efi partitions I was unable to enter legacy bios settings, through uefi bios.... (At that point I didn't knew that Smiley Sad(((  )

 

So thinking I will return to Uefi bios boot I've reset the bios by extrating the 3V bios battery...

 

After that no f2 or f12 during post an most bad at all No DVD booting. just the promt for entering password.

I understand from the password promt That legacy bios is OK but I'm unable to acces it

 

I tried to enter bios using every key ( ESC, F2, Del, F10, F12 ) no chance.

I tried to use an external USB keyboard no chanche either...

 

I'm LOST  Please Help me!

    It is odd you can't access the BIOS using F2. That is the key for BIOS entry on this system. The only ideas I have to try is to make sure the computer is in a completely shut down state. You can do this by holding the power key for 10 seconds until all LEDs are off. Then power on and tap the F2 key as soon as you see the Acer logo.

     

    Do you know if the function keys are actually working in situations other than getting into the BIOS?
