A friend of mine droped me off a Compaq Presario 2500 Laptop the other day. I asked was was wrong with and she told me that when she turns it on it won't boot to windows but boots to a blue screen. So I got around to looking at it today and sure enough it booted to a blue screen. So I stuck in the XP disc, set the boot order to CD first and went to format it. It loads up everything and gets to the partition screen. Now here is where it gets weird. Its not saying it has a C: drive. Where the letters are on the left its just =-= or something like that. So i hit enter to load it on the 40gb partition and it won't let me. Some how this computer lost its C: and I don't know how to get it back so I can format it. I've never ran into a problem like this. Can anyone help me out? Thanks.
