Hello. I am trying to Install Windows XP on my old PC. It didn't have a CD-ROM so I used one from my new Computer. The Problem I am getting is that whenever I connect the CD-ROM, computer doesn't boot. It Ends Up giving me error : "Disk Boot Failure, Insert System Disk and Press Enter" The Hard Disk is alright and does boot if CD-ROM is disconnected. However, After I connect the CD-ROM, Hard Disk won't Boot either, even when it is first boot device. CD-ROM is working fine on other PC and hard disk is also quite right when CD-ROM is not connected to the PC. I would really appreciate it if someone could help me out. Thanks.
