[Synopsis]
This video shows you how to fix a no boot device error. It may not work if your hard drive is bad, because that is a different problem altogether. Never the less, if your hard drive is dead you will get the same error. If you have 2 hard drives, and a optical drive in your computer. Let's say one hard drive isn't being detected then you can go into the BIOS to check if any of the sata ports are disabled or not.
Other times, someone may have played around with the BIOS and disabled sata ports, and if that happens the computer will not boot.
