Please do the following:

Get a look at the error message presented by the BSOD (blue screen of death) ....
  • Start tapping the F8 key after you press the ON button, and continue tapping until you are presented with the "Windows Advanced Options Menu" screen.

    Posted Image
  • Use the UP/DOWN arrow keys to select "Disable automatic restart on system failure" and press the <ENTER> key.
  • Your system will attempt to restart normally, but when it crashes, it will not re-start: Instead, you will see a BSOD with error message.

    Posted Image
  • Record the error message details (contained in the areas outlined in red, in the above example image), and post in your reply.

Re: STOP 0x7B

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.

Source: http://aumha.org/a/stop.htm

Was there any sign at all of a malware infection on the computer ... or have you had to deal with malware on the system recently? An infected MBR (Master Boot Record) can result in a STOP 0x7B error.

Another possibility is a change in BIOS settings, whereby the hard drive detection mode has been changed from IDE compatible to SATA (where you are using a SATA hard drive, and don't have the SATA drivers on the XP system). Please provide the full make and model details of the laptop (look underneath).

Let's check the MBR for a possible infection.

Please try the following: You will need a USB drive/flashdrive and a new blank writable CD.

:step1: Please do the following on a working computer:
  • Download GETxPUD.exe to the Desktop.
  • Run GETxPUD.exe
    A new folder will appear on the desktop.
  • Open the GETxPUD folder and click on get&burn.bat
  • The program will download xpud_0.9.2.iso, and when finished will open BurnCDCC ready to burn the image.
    Please be patient: This could take awhile - download file size 63MB.
  • Click on Start and follow the prompts to burn the image to a CD.
You will use this CD to boot the ailing computer from.


:step2: Boot the ailing computer with the xPUD CD.
  • (You may have to configure the Boot Menu or BIOS Setup Menu to boot first from the optical/CD/DVD drive.)
    A Welcome to xPUD screen will appear.
  • Click on File.
  • Expand the mnt icon on the left (click on the little arrow beside the icon).
    • sda1, sda2 etc. ...usually correspond to your HDD partitions
    • sdb1, sdc1 is likely to correspond to a USB flashdrive, external USB hard drive etc.
  • Click on the folder that represents your USB drive (sdb1 ?).
  • Click Tool on the top menu, and choose Open Terminal.
  • Type the following at the hash prompt:

    dd if=/dev/sda of=mbr.bin bs=512 count=1

    • Note: Leave a space between the following:
      • dd ... the executable application used to create the backup
      • if=/dev/sda ... the device the backup is created from (the hard drive when only one HDD exists)
      • of=mbr.bin ... the backup file to create - note the lack of a path - it will be created in the directory currently open in the Terminal
      • bs=512 ... the number of bytes in the backup
      • count=1 ... says to backup just 1 sector
        It is extremely important that the if and of statements are correctly entered.
  • Press the <ENTER> key.
    After it has finished a file will be located on your USB drive named mbr.bin.
  • Remove the USB drive from the ailing computer.

:step3: On the working computer:
  • Insert the USB drive, and navigate to the file mbr.bin
  • Zip-up the mbr.bin file:
    • Right-click on the file and choose Send to .. > Compressed (zipped) Folder.
      A zipped folder will appear in the same location as the mbr.bin file.
  • Please attach the zipped file to your next reply.
    This will allow the MasterBootRecord of your drive to be checked to see whether or not it is infected.

You did well: Thank you.

The MBR looks fine to me (mbr.bin viewed in a hex editor), with only one partition, which is bootable. If my calculations are correct the hard drive is 40GB in size: Can you confirm please?

The mbr.bin file was uploaded to virustotal.com and the results were 100% negative, so there is no indication of the MBR being infected:
That leaves me scratching my thinning scalp ... :scratchhead:

When you boot (or attempt to boot) into Safe Mode, what is the name of the last file that you see loaded on-screen? You can use the "Pause/Break" key to halt the loading process to get a good look at the screen text (use the Enter key to continue the booting process).

Please boot with xPUD and look at the contents of sda1 (file > mnt > sda1), your only partition. You should see all the files and folders there that you would normally see on C:\ drive when in Windows XP system.
  • Please provide me with a list of what you see.

mup.sys
Yes that is likely and means that phase of the booting process completed successfully.

Please confirm ... that when attempting Safe Mode, after showing mup.sys, the system crashes and restarts.
  • It doesn't just hang there?
    If it hangs for awhile before crashing and re-starting, how long does it hang?

Please boot into xPUD and navigate to:

File > mnt > sda1 > Windows <<< directory

and look for the file named ntbtlog.txt

Copy (right-click > Copy) the file and then paste it into the flashdrive (sdb1 ?).

Transfer the flashdrive to a working computer.

Please zip up the ntbtlog.txt file and attach the .zip file to your reply so I can have a closer look.
  • Right-click on the file > Send to ... > Compressed (zipped) Folder.
    The zip file will be located in the same place.
  • Attach the zip file to your next reply.
    When you click on Add Reply, you will see the facility to attach a file just below the box where you type your message.
