No Bootable Device

What does it mean?

The hard drive of the computer or the hard disk is the device where
the computer stores the secondary memory. All the movies, music, and
games in short everything stored by the user in the computer gets stored
in the hard drive. The operating systems are also installed in the hard
drive. So when the computer cannot find the hard drive during startup,
proper startup becomes impossible since the windows cannot load. The no bootable device error is then displayed on the screen.

 

 

Troubleshooting steps for desktops

The no bootable device error normally gets fixed by
rapidly pressing the F1 button. If it does not work, try and press F2.
The user shall be then redirected to the BIOS setup. In the BIOS setup,
if under the primary hard drive window, “none” is displayed, it means
that the computer cannot recognize that there is a hard disk connected.
This may be done due to some loose connections in the SATA cables which
can be easily fixed. If still the no bootable device error persists, this means there may be some problem in the hard disk.

If the F2 button trick does not work, you should check whether the laptop is still under the
warranty period. If it is, then the service provider must be contacted

should be removed. Hold the power button for a few times and ground the
motherboard, then if you don’t know how, get instruction manual from a
proper laptop disassembly guide and remove and reconnect the hard drive.
