Hi there.

So recently, a friend of mine had their laptop fail to load their Windows XP operating system earlier today. They found that they had a blue screen error appear. After some basic rigorous checks, whilst testing Safe mode, System Restore, Last known good configuration and Safe mode with Networking, all of these different options ended up with the same blue screen error appearing before windows had a chance to do anything. System restore, however, did briefly show it's general system restore background before ending up in the blue screen situation again. We've looked around the internet pretty well, and we can't find much on our actual issue. However, we do have information on the bluescreen of death error.

The error message is as follows: https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-snc6/v/735013_10200270478995289_88123601_n.jpg?oh=dc76e965790131c001cdb84a785a4861&oe=50FA053D&__gda__=1358667880_9c4b818b4a46b687fdff93843b73b0ac

The laptop make is: Toshiba NB500-11D

We think the cause is a result of my friend being notorious for closing a laptop down by holding the power button, I personally believe that she may of corrupted a critical system file whilst an installation was occuring on her computer.

What do you guys think? Any help would be appreciated.

Hello Rhys Jones


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

In this particular case it's a STOP: 0x0000007B (, 0xC0000034, , ):
  • "It means Windows lost connection to the system partition (0x7B) because the device object was not found (0xC0000034)." ... VirGnarus
Let's create a bootable LIVE Linux CD or flashdrive and have a look at some possible causes of this error.
  • Firstly we'll check the MBR (Master Boot Record) which commonly causes this error if it is corrupted (damaged or infected by malware).

:step1: On a working computer, please download the latest version of PartedMagic:
Write (in the appropriate manner) the downloaded .iso file to either CD or USB/flashdrive:

:step2: Boot the problematic computer from the PartedMagic CD or flashdrive:
  • At the first menu with Default settings (Runs from RAM) selected, press <ENTER>.
    Be patient while PartedMagic loads into memory, and then displays its Desktop.
Success? Let me know if you can successfully boot to the Desktop of PartedMagic, and whether you are using a bootable CD or a flashdrive.

The Desktop of PartedMagic (version 2012-08-09)

:step3: At the PartedMagic Desktop, open a terminal window:
  • Locate the black screen/monitor icon (ROXTerm) along the bar at the bottom of the Desktop screen (third icon from the left-side edge).
  • Click on the ROXTerm icon to open a terminal window and at the prompt, type:

    fdisk -l

    Note: There is a space between "fdisk" and "-l".
    That is a lower case L as in Llama and not a ONE.

  • ... and press <ENTER>.
  • Drag your mouse over the output to select it all.
  • Right-click somewhere in the area selected > Copy
    (In the next step, you will paste this in a reply.)
At the PartedMagic Desktop:
  • Double-click on the Firefox icon to open the Firefox browser window.
  • Enter the BC forums address www.bleepingcomputer.com/forums in the address box and press <ENTER>.
  • Sign in to the forums and locate your topic.
  • Paste the text that you copied in the terminal window in a reply to your topic.

    Note: Please enclose the pasted text in CODE tags so that the spacing/formatting is preserved.
  • Firstly, click on the "Insert code snippet" button Posted Image
  • You will then see the "start" and "end" code tags (highlighted in dark blue/selected in the image) in the text box.
  • Click between the two tags to insert the cursor between the tags and then press <Ctrl+V> to paste the text there.

:step4: At the PartedMagic Desktop, open a terminal window:
  • Click on the ROXTerm icon to open a terminal window and at the prompt, type:

    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.
[*]... and press the <ENTER> key.
A file named mbr.bin will be saved to the system in the "root" directory.
Note: This file is saved in memory only and will no longer exist when PartedMagic is shut down.
[/list]At the PartedMagic Desktop, double-click the File Manager icon (on Desktop):
  • A new window will open.
  • In the "root" directory you will see the file that you just created called mbr.bin.
  • Right-click on the mbr.bin file > New > Archive.
  • Under "Archive Format", choose the format .zip from the drop-down menu.
  • Click Save.
  • You should now see the zipped file, mbr.bin.zip in the root directory along with mbr.bin.
Please attach the mbr.bin.zip file to a reply to this topic.
  • When you click on Add Reply, you will see the facility to attach a file just below the box where you type your message.
