Hi, I am trying to diagnose a problem with a computer I offered to "fix". The owner was unable to load Windows XP withotu having the XP install disk in the drive. The OS would load and run fine as long as the computer booted with the CD in the drive. I partitioned the drive, copied the personal files to the new partition and formatted and installed XP on the first partition. I encountered one problem while installing and it was along the lines of: "IRQL_DRIVER_IS_NOT_LESS_THAN_OR_EQUAL" Which would appear in a BSOD during the Windows install. I swapped out the RAM and was able to complete the install. Now, on a fresh installation I am getting this error: "DISK BOOT FAILURE. PLEASE INSERT SYSTEM DISK AND PRESS ENTER" when I don't have the XP install disk in the drive. Does this mean that the hard drive is probably dying? When the XP disk is in the drive the computer runs fine. It's also crazy that both the memory and the hard drive would fail at the same time.
