While starting up the computer, you will come to the chance to get a “No bootable device” error message in the following formats:
* No bootable devices–strike F1 to retry boot, F2 for setup utility
* No bootable device. Reboot or press any key to retry.

Typically, this error means that the computer can’t find your hard drive so as to boot up your computer properly. We know that the hard drive is where all data including files, programs, photos and everything you saved on the PC; if the “No bootable device” error message cannot be solved timely, it may not only stop you from booting up the computer, but also seriously cause unexpected data loss.

To troubleshoot the “No bootable device” error, press F2 or whatever the computer suggests to enter BIOS setup. Sometimes, you may enter the BIOS setup by pressing the “del”, or F10 key. Then, check the option labeled “Primary Hard Drive” to see what it shows. If it says “none”, then there is no doubt that your computer doesn’t even recognize that a Hard Drive is connected. Just keep on reading for more detailed info on how to fix it.

Then, you should unplug the power cable, remove the battery and anything else plugged into the computer: mouse, USB drives, etc, and plug them back to see whether they solve the problems. In many cases, a loose connection of such hardware device can also bring in the “No bootable device” error message. However, if all these are plugged firmly but you still get the error message, try removing the Hard Drive and placing it back again to see whether it solves the problem.

Thirdly, if nothing goes wrong with the additional hardware devices, the problem may exist on the computer itself. And the thing you need to do right now is to completely check & make sure no problem or bad sector exists on the hard disk:

*Click on Start -> Computer.
*Now right click on the drive letter that you want to scan & repair and select Properties
*Click on ‘Tools’ tab and then ‘Check Now’ under error-checking section.
*Within the appearing window, you will see two options. One option is ‘Automatically fix file system errors’ and other is ‘Scan for and attempt recovery of bad sectors’. You are suggested to tick both checkboxes so as to completely scan & repair all errors existing on your computer.

Fourthly, make sure the computer is totally virus clean. We know that it is quite common for a PC virus to result in any of these problems: slow running computer, various popping up unknown errors including the “No bootable device” or Windows error 0X80070570 at PC startup, constant ads windows, random PC reboots, or blue error screens, etc. No matter whenever you find the computer run abnormally, run your antivirus program immediately to get rid of all existing & potential viruses. A virus-clean computer is what you should make sure so as to run the computer properly.

Last but not least, check and repair registry errors. Over time, the registry can be full of invalid entries to make the computer run slowly or something worst. In many cases, such invalid entries will be the result of incomplete program install/uninstall or a virus or other unwanted software that has made its way to our computer without your knowledge. If the system cannot locate the required entries to start up the computer or access the needed hard disk, a “No bootable device” error message will display. Thus, you have to completely scan the whole PC and repair all registry errors as quickly as you can.
