Quote - If you have two hard drives or just upgraded a hard drive, or even bought an external drive, it could be trying to boot from that, go to your bios, if any of the above apply and find boot settings, make sure it is booting from the correct drive.

Either way you need to enter the bios, which could be by pressing F1,F2 or maybe DEL, and see if you hard drive is even detected.

I've been running 2 internal and several external drives since I've had it so it wouldn't suddenly want to boot from one of the others would it?
