Well, the good news is that your system is still detecting your hard drive. The bad news is that your Windows installation is corrupted somehow.

If you're using System Restore, you could try booting in Safe Mode by hitting F8 a few times while the computer is starting (after the BIOS screen, where it mentions RAM information, but before the Windows logo comes on). If you get a menu, choose Safe Mode, then use System Restore to go to an earlier restore point.

It isn't always, but it's usually an indication of a failing hard drive. If you have important information on that drive that you haven't backed up (tsk, tsk), you should really do that, in case it's about to crash completely. You didn't specify the model of the laptop, so it might be a SATA drive, but it's probably an old, IDE one, in which case you'd need a 2.5 - 3.5" converter, and you'd need to set that up in a functional PC as a slave drive. Otherwise, pay someone else to do it for you (are you in the Chicago area? If not, are you someplace warm and willing to pay for travel? Please?).

Then, try repairing Windows. Boot from a Windows CD, the select the installation and press R for Repair.

    If the Repair doesn't work, backup all your files and make sure you have all your software on disks, then, depending on it's age with Dell PC's it may have a recovery partition.

    try this : During the computer startup press and hold the CTRL + F11 keys

    Follow the instructions for Restore to Factory Settings

I have a blue screen that says "UNMOUNTABLE BOOT VOLUME" And system will not boot up any further?

This means that the hard disk drive has a problem. It could be an electronics failure or it could be a driver problem. Try to start the computer in SAFE mode by pressing the F8 at bootup. This will verify the hardware.

My dell computer when i start it up goes to a blue screen it says windows did not start propperly then it takes me to a blue screen and says unmountable boot volume

You need to repair the Master Boot Record. This is a fairly complicated procedure so if you are not confident in your computer skills, this issue is worth hiring a professional to handle.
What you will need is a bootable CD, such as a PE application, which you can use as a platform to run checkdisk.
Boot from this CD and then un-mount your internal hard drive. Run CheckDisk (chkdsk command on cmd) with both of the parameters /f and /r
This should go through your hard drive and repair your MBR.
Reboot your computer and you should be good to go.

If this does not work, run a repair-reinstall. This reinstalls all system files including your MBR and bootable files on the X drive.

Good luck, please rate my solution!

Unmountable boot volume is most likely an indication of a failing hard drive. Boot to your Windows CD and run CHKDSK /R and see if issue resolves. If it doesn't then you are probably replacing the hard drive.

You need your Windows XP cd for this fix.

Boot from the Windows XP CD and at the first prompt, press "r" for repair. Press 1 when asked to choose windows installation and then enter the admnistrator password. If you don;t have one, just press "enter" and it should show you "c:\windows>"

At this prompt, type the following

chkdsk /r

THis should take quite sometime but will fix the problem at the end. when you get the c:\windows prompt again, type the word "exit" and your system will reboot and load windows XP normally

Blue screen during booting

Yes, unmountable boot volume usually means you need a new hard drive. However, if you have a windows xp cd, you can boot to the recovery console (press R at the first prompt) and try running a chkdsk /f command. Sometimes that will help. Thanks and good luck! Oh and if you could remember to give this solution a rating of fixya. Thanks!
