When you start Windows XP, you may receive the following error message:
STOP 0x000000ED (0xaaaaaaaa,0xbbbbbbbb,0xcccccccc,0xdddddddd) UNMOUNTABLE_BOOT_VOLUME
Note In this error message, aaaaaaaa, bbbbbbbb, cccccccc, and dddddddd are hexadecimal numbers that may vary.
This behavior can occur if the file system is damaged and cannot be mounted.
Damaged File System
If the second parameter (0xbbbbbbbb) of the Stop error is 0xC0000032, the file system is damaged.
If this is the case, restart the computer to the 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, follow these steps:
1. Start your computer by using the Windows startup disks, or with the Windows installation disk if your computer can start from the CD 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 this.
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.
You will need a regular windows XP cd for this.
