i have recently attempted to fix an older computer for backup and am running to some issues. I attempted to change the hard drive for a larger and quieter one. I have formatted the new hard disk and installed it in the computer as the master. it is plugged into the primary ide slot and is being recognized fine in cmos. the cdrom is plugged in to the secondary ide slot and is also set as master. I am getting a disk boot failure- NTLDR missing- please enter system disk and hit enter. I have changed my boot sequence to CDROM,C,A to no avail. I have also tried to auto detect in setup page and it is not being recognized, I have also swapped to another drive that I know is working. Is there something that could be turned off, I just need to be able to boot from my XP cd to reinstall.
