Top fixes for “Boot device not found” error

For most cases, the first method below will do the trick, and I’d personally suggest you go with that one. It might, however, take a while. So, you can always try one of the more popular methods below to see if you can hack your way into Windows. Let’s begin.

1. Reinstall your Windows 10 or Windows 11

Since the most probable cause of the “Boot device not found” error is trouble with your Windows operating system, the natural way out of it is through reinstalling your operating system.

For this, you’ll need a bootable USB stick. If you have one, great. Otherwise, you’ll create one on another PC. We have created a detailed guide on creating a bootable Windows USB stick. So give that a read, and learn how to do it well.

When you’ve a fresh Windows USB stick ready with you, plug in the USB stick, start up your PC and hit the Esc/F10/F12 key. You’ll be taken to a new boot menu, where you’ll get the option to either install a fresh copy of Windows or repair the existing one.

Go with installing the complete Windows option. From there, simply follow the on-screen instructions, and you’re good to go. The whole process can take anywhere from thirty minutes to a full hour. So make sure you set aside a block of time for doing this.

2. Do a Hard Reboot

A Hard Reboot, sometimes also called cold reboot, is a process of rebooting your PC forcefully by pressing the power button. It drains the electricity in remote parts of your motherboard, and from there, you can start everything afresh.

To carry out a Hard Reboot, press and hold the power button of your PC for about 10 seconds. Your computer will turn off on its own in a while—then, when the power is off, wait for a few seconds and turn it on back again.

Fixing the “Boot device not found” error for good
