Hey guys! I've just got a new computer and I'm trying to install Windows Xp. I format the drive and setup copies the files. It then restarts(thats normal) and when it boots up its supposed to enter windows Xp. But it only loads the setup again! And when I boot from HD, it says invalid system disk. I can't get Xp! By the way, I have a 2.66Ghz P4 and a P4S800 Mb and 512 mb of RAM and 80Gb hard drive.
