Windows 7: BSOD

STOP 0x0000007B: INACCESSIBLE_BOOT_DEVICE

Usual causes: Hard drive, File system, Boot sequence errors, Device driver, Virus infection (in particular check the MBR)


Are you able to boot to the recovery disk? If you can, I would like you to go into the command prompt and run a chkdsk /r on your drive. Once you finish that run a bootable hard drive scan.

HD Diagnostic

EDIT: I was re-reading your posts. You state when you load the BIOS there is a password. Has there always been a password? How have you been changing the boot order?

Hi yes i can boot from recovery CD and at some point I see the following options (see image 63 ). I can go to command prompt (last option) but when I run chkdsk /r it , it gives me an error. See image 64. I am sure I am doing something wrong ...

As far as the Bios Admin passoword (I added an image 65), not sure if the password has always been there since i never had to go into the Bios before but as far as changing the boot order, it gives me the option to do right at the beginning when i press ESC (see image 67) F9. from what i understodd this allows u to decide the root order that one time but doesnt change it in general as it would if u do it in the BIOS.

go into command prompt
then type "diskpart"
type "list volume"
then "select volume xxx" (where xxx is the write protected problem drive)
then type "attributes volume clear readonly"

Can you run memtest again on the new memory.

Re-run the chkdsk and report back the results

ok run memtest again on the new memory and it gave zero error.

Also re-run the chkdsk /r on both C: and D: and both resulted with file system checked with no problems found.
