Unmountable Boot Volume

By trandel ·
My daughter has a problem on her Dell Dimension. She gets the above message trying to boot up her desktop after a power failure. We have tried to use the recovery system console route but it just freezes after the 'Welcome to XP Setup' screen.

Short of removing the HDD and installing it on another desktop to run chkdsk are there any other suggestions?

Regards

Tony Randell

Tony,

I would try to start up in save mode by pressing the F8 button at start-up.

Then you should run a complete disk check in order to recover unallocated datablocks.

If that fails you need to start up with the help of a start-up disk. Then try to run the disk check.

You also can make a start-up disk from another workstation. Use HELP to see how you should do that.

Regards,

Harm Losekoot

Hi,

Safe Mode does not work at all and neither does the CD.

Remove the battery for about 10 minutes, then reinsert and retry the computer. Sounds silly, but this has worked for me before. Dell has a technical explanation if you care to visit their web site.

Repost if these don't help.

sounds like it's possible the hd is not being recognised or 'detected' by the hard drive controller in the dell. if you press tab or esc during bootup while you see the dell logo, you can see 'behind' the logo and watch the boot up process. you will see the video bios announce (you might miss that it is very beginning) you will see the hard disk controller find the drives. probably a cd drive and a hard drive are hooked to the controller. in particular you should see something with a model name you can identify as the hard drive.
if you dont see this, that is maybe a good sign.
reboot again and watch the screen and enter BIOS setup. go the dell website and search support with the service tag number for exact steps to enter Setup and force redetection of the drive.
here is an article about it. if this is the case, she needs new cmos battery ...

I dont think that I was too clear in explaining the problem - She cannot boot at all even in safe mode so we have tried to boot from the CD supplied by DELL. That is when the recovery console (or whatever as you cannot even quit!) fails after the setup screen inviting a response of enter, R or quit.

The only time that I have seen this message was working with Red Hat's version of linux.

if you have an old dos boot floppy you might be able to get it to recognise the drive, if you used a fat 32 instead of the corrupted ntfs that xp uses by default.

to get access to the data, you are going to havce to connect the drive as a slave in another box, save what data you need, then rebuild the entire partition on the hard drive.

when the power went your daughter's system must have been updating the file tables in the partition, and it damaged the partition data enough to prohibit using as a boot partition.
