I've already backed up my data, what I can of it anyway. I was ready to go get a hard drive tomorrow, but I thought I'd get a detailed opinion in case there was some simple thing that I could fix myself that I wasn't picking up on. I only have recovery discs. I have a Compaq Presario SR1750NX and the website claims that I can format a new drive with them. I printed off the instructions and I'm hoping that it works because I'll be more than broken hearted if I have to buy Windows XP. I paid for it with the blasted computer didn't I? I should be able to load it onto any hard drive I want.
