Well, after deleting the wrong partition (which happened to be my other hard drive, which had to be the one with all my files backed up) after formatting my hard drive, i now cannot even install Windows. I did this trying to re-install windows xp, and now when i try to install it to the newly formatted NFTS hard drive (not quick format, the one that takes an hour) it copies all the files, reboots, and gives me a "A disk read error has occurred. Press CTRL+ALT+DELETE to reboot"

I've googled this a lot, but haven't found anything having to do with win xp setup. nothing was wrong before i did this.
can anyone help me out? i really need to get to installng win xp for work!! thanks.
