First ensure that you have no CD inside, and that no USB memory stick is plugged.
case one : you get "a:\No system disk or disk error" prompting that there is no floppy. Even if there is no floppy on the machine. That is because BIOS has a virtual A: drive.
Go to bios settings and change bootup sequence put C:\ first
Case two, the system cannot boot and you have generic "No system disk or disk error" because it cannot load the system from C:\ drive.
In this case try reinstalling the system using windows install disk or a recovery disk. If it does not work, the disk may be damaged, and you will need to have it replaced or formatted.
