0x0000007B: INACCESSIBLE_BOOT_DEVICE
(Click to consult the online MSDN article.)
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.

Did you recently update a driver?
Have you tried a system restore back a day or two before the issue started?
Do you have a XP installation disk? If so try the following:

If you have Windows XP CD...

1. Boot from the CD.
2. When the text-based part of Setup begins, follow the prompts. Select the repair or recover option by pressing R:



3. You'll find yourself at this screen:



4. Once you are at the Recovery Console you will be given at least one choice of Windows installations. Normally the choice you want is the number 1 choice. Click the number 1 key at the "top" of the keyboard and click enter.

NOTE: at this point your numbers to the right of your keyboard are turned off. If you insist on using these keys for your numbers remember to hit the Numbers Lock key before clicking a number over there or your computer will automatically reboot and you will have to wait through the previous steps to get back to the console.

5. You will be given a message asking for the administrator password. Unless someone or something has messed with your computer there is no password so you just click the Enter key.

6. This will bring you to a prompt that says:

C:\WINDOWS>

7. Type:

cd \

Press Enter

Note: between "cd" and "" there should be a "blank space" otherwise the command won't work

8. The prompt should now say:

C:\>

9. Type:

cd system~1\_resto~1

Press Enter.

Note: If it gives an error "Access Denied" while accessing the folder, follow the method below

Type: cd \

Press Enter

Type: cd windows\system32\config

Press Enter

Type: ren system system.bak

Press Enter

(note the spaces between ren and system, and then between system and system.bak)

Type: exit

Press Enter

now the computer should restart, then follow steps 1-6

10. Type:

dir

Press Enter

NOTE: When you hit enter it will list all the restore points folders like "rp1", "rp2" we have to see the last restore point to copy the file from a recent backup. If the restore points have more than one page then you have keep on hitting the key to view the last restore point folder.

NOTE: It is a good rule of thumb to choose the files from the restore point folder which the second to the last one.

11. Type:

cd rp{with the second to the last restore point number }

Press Enter

Example: cd rp9. if rp10 is the last restore point

12. Type:

cd snapshot

Press Enter.

NOTICE: Now the command prompt will look like this:

c:\system~1\resto~1\rp9\snapshot

Note : restore point 9 assumed for clarity of the content.


13. Type:

copy _registry_machine_system c:\windows\system32\config\system

Press Enter

14. Type:

Exit

Press Enter.

Final note : If the above procedure won't solve the problem, repeat all steps, but in step 13 type:

copy _registry_machine_software c:\windows\system32\config\software

Alternatively, select different restore point.

Thanks, the machine is back up and running, lost some documents and picture files, but no worries.

lost some documents and picture files, but no worries.

Strange as normally a repair installation doesn't lose any data but depending on what files it had to repair it may have.
I'm glad to hear you are back up and running with minimal loss of data.
Please let is know how it all works out and if you have any further questions or issues.

Congratulations. for a successful resolution for your issue.

You are very welcome.
