my computer is an msi k9n neo v3. when i got on it one day it said reboot and select proper boot device. so i put in the windows xp pro disk and then it said "setup did not find any hard disk drives installed in your computer. make sure any hard disk drives are powered on and properly connected to your computer and any disk related configuration is correct. how can i fix this problem without a floppy disk or using anything long and confusing?
