Blue Screen Variation

Problem!!!!!

STOP: 0x000000ED (0x81796E30, 0xC0000006, 0x00000000, 0x00000000)

Solution.....

The second parameter (0xbbbbbbbb) of the Stop error is 0xC0000006 which says UNMOUNTABLE_BOOT_VOLUME.

If you are lucky enough then the procedure given here will work.
But this won't work in around 90% of the cases. Any how this is worth trying.
If this procedure fails try the alternative described below.

In this case, restart the computer use XP installation CD to get to recovery console and then use the chkdsk /r command to repair the volume. After you repair the volume, check your hardware to isolate the cause of the file system damage.

To do this, use the following steps:
1. Start your computer with the Windows startup disks, or with the Windows CD-ROM if your computer can start from the CD-ROM drive.
2. When the Welcome to Setup screen appears, press R to select the repair option.
3. If you have a dual-boot or multiple-boot computer, select the Windows installation that you want to access from the Recovery Console.
4. Type the administrator password when you are prompted to do so.

NOTE: If no administrator password exists, press ENTER.
5. At the command prompt, on the drive where Windows is installed, type chkdsk /r, and then press ENTER.
6. At the command prompt, type exit, and then press ENTER to restart your computer.

If this procedure does not work, repeat it and use the fixboot command in step 5 instead of the chkdsk /r command.

Alternative:

The problem you mostly face about the procedure above is that

• you may not be able to access C drive a.k.a. the windows installation drive. (or)
  
• you may get to access the C drive but the file system is not recognized. (or)
• your windows installation is not recognized. (or)
• "autochk.exe file is not found. Please enter the path where file is located".
  

whatever the case is you are not supposed to format the drive because there is still chance of recovering the installation.
