Please help me, I have no idea where to go from here.

I ran a virus check on my computer and it suddenly came up with that irritating blue screen saying 'unmountable boot volume'. I have tried countless number of tims to run it in safe mode and when that failed, I tried to reboot the system but there is absolutely nothing I can do to get that annoying blue screen to budge. All I know is it says unmountable boot volume. Any help would be much MUCH appreciated.

NB. ive heard about the reboot console but I dont nkow what it is or anything.
Please help!!

Yeah, sounds like it could be the boot sector

see if this is you:
STOP 0x000000ED UNMOUNTABLE_BOOT_VOLUME" Error Message When You Restart Your Computer or Upgrade to Windows XP

When you first restart your computer during the upgrade to Windows XP or when you start Windows XP, you may receive the following error message, where aaaaaaaa, bbbbbbbb, cccccccc, and dddddddd are hexadecimal numbers that may vary:
STOP 0x000000ED (0xaaaaaaaa,0xbbbbbbbb,0xcccccccc,0xdddddddd) UNMOUNTABLE_BOOT_VOLUME

NOTE: If you receive this error message when you restart the computer for the first time during an upgrade to Windows XP, your original operating system still works correctly. In some cases, a message appears on the BIOS report screen that states that the wrong cable is in use, but you may not see this message on computers that have a fast startup time.
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: ? 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.
? The basic input/output system (BIOS) settings are configured to force the faster UDMA modes.

? The file system is damaged and cannot be mounted.

To resolve this behavior, use the appropriate method.
UDMA Controller
If your computer uses a UDMA hard disk controller, use the following procedures: ? Replace the 40-wire cable with an 80-wire UDMA 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.

Damaged File System

This will make your day if you are running win2000 or xp.

First disconnect all hard drives except the boot drive. Boot to a win98 boot floppy with fdisk on it.

Now at the command prompt type "fdisk /mbr" of course don't type the quotation marks.

This will repair any damage that has occured to the boot record. Shut down your system and reconnect any drives that were disconnected.

Now boot into your bios and set the boot sequence to cdrom first. Put your os disk in the cdrom and reboot. At the prompt hit a key to boot from the CDRom.

Your system should be ready to go.

Good Luck Lee

Follow the directions in the Knowledgebase Article for your OS. The links are provided.

This will perform an Inplace Upgrade to your system. It will replace all of the system files and rebuild your system. All of your programs will be maintained.

Another possibility is to get you operating system CD, and boot from it. It will run you through the loading of files and such, then ask whether you want to install windows or repair windows.

Use the repair option and select the option to repair with the recovery console.

This will start the recovery console and it will ask you for an administrator password (lets hope you know it!)

You can then run Chkdsk with the appropriate parameter - type chkdsk /help and it will tell you. I think it is /r from memory.

That may fix your problem if you are lucky.

Good Luck,

Boot from Win XP CD and enter Recovery Console when prompt appears (setup stops and prompts you to press R for recovery console).

Run these two commands after you enter the rocovery console ("DOS prompt").



Remove XP CD, type exit to quit revovery console and reboot. Cross fingers and hope. If you're lucky, the system will start.

If this approach fails, try connecting hard disk to another XP or Win2K PC. The OS should recognize errors on hard disk and try to correct them. I've had more success with this approach than with recovery console.

Norton Utilities (2002 or later) may help also.
