Please post the exact model number of your system. Now it is possible that you are having HDD/SSD problems but first of all run diagnostics (tap F12 immediately at boot) and watch for any drive errors. If no errors are displayed it could be a matter of corrupt Windows system files. This forum post has a number of suggestions that may help as well.

Now, you can try the below-listed methods to check if the "no bootable device found" problem can be fixed.

Method 1. Remove and connect back all hardware components
Method 2. Check boot order
Method 3. Reset primary partition as active
Method 4. Check internal hard disk status
Method 5. Fix boot information (BCD and MBR)
Method 6. Recover deleted boot partition
