Help! Disk Boot Failure

[Mr. Os]

Today, I was trying to replace my power supply for my gaming computer, I successfully installed it, but now i get an error 'Disk Boot Failure, insert system disk'. I have no idea what this means, and I'm pretty sure I've ****ed up my gaming computer, I just want to know how to solve this problem.

I also have no idea what it means by system disk.

You sure you plugged the molex connector into the harddrive. If you have check you have it properly seated, if still no responce it sounds like you fried it.

I agree with Donno, check the connector that goes into the back of the hard drive, sounds like a loose fitting.

Could happen if a loose cable is in contact with the motherboard. Check to make sure all cables are properly seated and claer of the motherbaord.
