I just have installed new motherboard and CPU (and memory). I didn't format my hard disk drive before I installed the new motherboard. And I figured out that I must reinstall the Operating System. It seems like my floppy drive is not working so I have set BIOS to first boot with CD-ROM. I have tried to boot up the install program of Windows XP but it would give me "Disk Boot Failure" and wouldn't start the installation program. Is it because my hard drive is not formatted? How can I format my hard drive and how can I start the installation program??
