Yep, find a bootable Windows Environment such as the Ultimate Boot CD (free).

I use BART from Avast, they have a 30-day free trial but it's not a free product.

All you'll need to do is boot with one of these CDs (they usually carry a full copy of Windows XP), copy the important files off onto an external USB hard drive, and then you can nuke-and-reload your system.

If that for some reason isn't an option, you can rip the hard drive out of your computer, plug it into an external IDE enclosure or USB connector (they're about $25), plug it into another computer's USB port, and copy the data off onto that computer.

It means your HD is either close to, or dead.

I would find attach it to a friend's computer and copy important stuff off it ASAP

As others say, your disk is nearly dead. So, if you have problems getting data off the disk, try some bootable LINUX sollution, like Knoppix. Burn Knoppix CD on your friend's machine, connect another (healthy) disk to your machine and boot your machine from this CD.
You will have a chance to get almost all the data, but it *might* be that some very long filenames will be renamed to some reasonable shorter version.

Weird, I thought I had a valid solution to this one first. :\
