Put Linux back on and the boot loader will fix this.
Ok, I screwed up big time. I put Linux on y bro's pc running Windows XP home Edition and then took it off by means of deleting the partition it was on. Now when I start up the computer it just says GRUB Error 17. I know what that error is, I just need to know how to fix it. I did not delete the partition with Windows on it. Someone please help.
