Authoritative summary from http://www.aumha.org/a/stop.htm:0x0000007B: INACCESSIBLE_BOOT_DEVICE
Windows lost access to the system partition or boot volume during the startup process. Typical causes: Installing incorrect device drivers when installing or upgrading storage adapter hardware, or a virus.
First thing I would do...check all connections for my hard drive...ensure that the hard drive is properly detected in the BIOS.
After that, I would concern myself with moving valued data files from the hard drive to another system, another drive, etc..
Then...I would try one of the following malware scan ideas from CD: http://www.malwarebytes.org/forums/index.php?showtopic=5736
That concluded, I would try to run chkdsk /r from CD.
