    Re: error message: UNMOUNTABLE_BOOT_VOLUME

    Technical information about the error
    This section provides some technical background about the cause of this error message and why it might be generated.

    This behavior can occur if either of the following conditions is true:

    • Your computer uses an Ultra Direct Memory Access (UDMA) hard disk controller, and the following conditions are true:

    1. You use a standard 40-wire connector cable to connect the UDMA drive to the controller instead of the required 80-wire, 40-pin cable.
    2. The basic input/output system (BIOS) settings are configured to force the faster UDMA modes.

    • The file system is damaged and cannot be mounted.

    The purpose of this error message is to prevent the following two things:
    • Potential data loss caused by using an incorrect IDE cable for the faster UDMA modes. An IDE cable is a kind of cable used to connect storage devices, such as hard disks, inside a computer.
    • Continued access to a drive on which the file system is damaged

    Repair the volume
    Note the second parameter (0xbbbbbbbb) in the error message. You might have to regenerate the error in order to write it down.

    If the second parameter (0xbbbbbbbb) of the Stop error is 0xC0000032, the cause of the error is that the file system is damaged. You can try to repair the volume to see whether this resolves the error. If the second parameter is not 0xC0000032, see "Method 2: Check the IDE cable and load Fail-Safe settings" for help.
    Some things that you should know before you try this solution

    • If the file system is damaged, you can use chkdsk /r command to repair the volume. However, if you use the chkdsk /r command, you may lose some data.
    • You will need the Windows startup disks or the Windows installation disk. If you do not have them, contact the computer manufacturer for help in obtaining the disks.
    • You will need the administrator password to complete the steps.

    To repair the volume, follow these steps:

    1. Start your computer by inserting the Windows startup disks or 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.
    7. After you repair the volume, check your hardware to isolate the cause of the file system damage.

    If this procedure does not work, repeat it, but type fixboot instead of chkdsk /r in step 5.

    If you are still unable to resolve the issue, please see the "Next steps" section for help.

    Re: error message: UNMOUNTABLE_BOOT_VOLUME

    Check the IDE cable and load Fail-Safe settings

    If your computer uses a UDMA hard disk controller, try these steps. If your computer does not use a UDMA hard disk controller, see the "Next steps" section for help.
    • If your UDMA hard disk is connected to the controller with a 40-wire UDMA cable, replace the cable with an 80-wire cable.
    • In the BIOS settings for your computer, load the 'Fail-Safe' default settings, and then reactivate the most frequently used options, such as USB Support.

    If you are not sure how to follow these steps, contact the manufacturer or refer to the user’s guide that was included with your hardware.

    Re: error message: UNMOUNTABLE_BOOT_VOLUME

    This message does not necessarily mean that the hard disk is defective, it may be simply a problem in the boot sequence of the disc.

    To remedy this, simply do the following (no need to reformat the hard disk):

    • Insert the Windows XP CD and boot it. (so you can boot on a CD read the article change the boot sequence)
    • When it comes to giving the interface between the choice "between facilities" and "R reparation", press "R".
    • In the Recovery Console, enter the following command CHKDSK / R / P
    • Once the analysis is complete, enter the following command: fixboot
    • Remove the Windows XP CD drive and restart!
