1) The only message is Disk Boot Failure insert system disk and press enter. Prior to that the boot up goes through the sequence of IDE primary master and slave, pci device listing, verifying DMI Poll Data and then the DB failure message.
2) There is no floopy disk in the drive. I know what you mean like everyone else at some point we have made that mistake.
Just a thought but it could be that Windows is trying to load a bad or incorrect device driver of some sort.Have you recently added some hardware or software to your system ? If so check that you have the correct drivers installed.
curlylad, thanks for taking a look. To be honest I am not sure what to look for to determine whether the hard drive has been detected. Also we have not made any recent changes like adding hardware or software.
