is normal when the CD is before the C drive in the boot sequence, an d ignoring it is correct.
I wish that you would describe the actual problem in more detail.
My desktop started doing this intermittantly a while ago. I'd try booting again and it would eventually boot successfully. However, eventually it quit.
I recall having this problem when there was a bad Master Boot Record. Fixed it and no further problems. This time is different. Rewriting the MBR doesn't fix it.
Since it was time to clean up my HDD, I reinstalled Win XP Pro. This involved formatting the drive. Still - same problem.
I can still use the PC by leaving my XP CD in the drive. During the boot sequence I am prompted with "Press any key to boot from CD." If I ignore the prompt and let the boot sequence go on, I'll be able to boot right to my hard drive.
