Ok i have built a computer and i am trying to install Xp pro on the new comp. I have a brand new WD 40 gig hard drive. I have set the bios so that it only recognises the cd rom. I exit and save the bios and i insert the XP cd: i get and error message of " Disk boot failure insert system disk and press enter" can anyone please help me. Do i need to do something to the hard drive i am lost!!!! Also i dont have a floppy drive all i have is a CD rom. I am running a Asus A7n8x, ati pro video card, AMD 2500. and a WD 40 gig hd with 512 mb of ram.
