Constant Bluescreens and unable to select between modes

[Deathed]

Sorry about making yet another thread but I'm afraid I was rather unclear in the previous post

I was screwing with the BIOs when I found that now I am unable to get past a blue screen so first I tried to reset the battery but now my keyboard and mouse will not work so I cannot even choose between Safe Mode, Last Known Configurations, Or Start Windows Normally

The bluescreen says as follows

UMOUNTABLE_BOOT_VOLUME

STOP: 0X000000ED (8A46DE30, 0xC0000006, 0x00000000, 0x00000000)

The boot hard drive may not be selected properly in the bios... Especially if you have more than one hard drive installed. What operating system are you running?
