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.
