When I start my laptop I get the following error:
No bootable Devices press F1 to retry, F2 for setup, and F3 for Scan.
When I insert a Windows 7 install CD I get the same problem.
My laptop can't boot from the HDD either.
How should I proceed?
EDIT: Before you begin ensure that your physical devices are connected. This involves opening the housing of your computer and checking the cables that connect your HDD / DVD Drive to the motherboard so do not attempt to do so unless you either know what you are doing or don't care if you break something.
