In this tutorial, I will be demonstrating a number of ways to fix the problem of no operating system found in Windows, be it Windows 10, 8, or 7. Depending on the make and model of your laptop, this error message could be a bit different for you, for most laptops it would say “No operating system found”, for some it would say “No bootable device found” or “No Boot device found”. To avoid any further complications to your computer, I will advise that you follow these suggestions in the order in which they are presented.

1. Check out for is a loose connection between your hard drive and the motherboard.
2. Check your boot priority order.
3. Change from UEFI to legacy or CSM boot mode from the BIOS or vice versa.
4. Reassign primary boot device (Needs a bootable windows USB).
