I have a system on which there is only one HDD with XP loaded but the system is refusing to boot without the XP installation CD in the CD-ROM drive. This is a new system that was under construction and the only time XP was booted was with the installation done by the CD in the CD Drive. After we power on and we get the error message “DISK BOOT FAILURE – INSERT SYSTEM DISK AND PRESS ENTER” and we put the CD in and press enter – sooner or later the system is running on the XP loaded on the hard disk and we can take out the installation CD to no interruption on the XP functioning itself. How do I get rid of the need to have the installation CD in the ATPI CD ROM drive. I have even tried uninstalling and taking out the CD drive but then the system just doesnt load any XP till the CD is put right back in place. I have tried doing bootconfig application but it is not working. How can I remedy the disk boot failure and get going with what I have got on the HDD or a fresh install and not have to depend on the installation CD for every boot.
