Several factors can contribute to this error. Here, we outline several general causes of this issue:

6 Fixes: Selected Boot Device Failed Windows 10/11

Now, get rid of worries by applying the following quick fixes. Please follow the methods and steps carefully.

Fix 1. Change the Boot Order

One of the primary reasons for the "Selected Boot Device Failed" error is an incorrect boot order. Follow the steps to change the boot order:

Step 1. Restart your computer and press the appropriate key (usually F2, F12, or DEL) to access the BIOS settings. On your PC, the key could be different.

Step 2. Locate the "Boot" or "Boot Sequence" settings inside the BIOS.

Step 3. Here, it's essential to move the drive you intend to boot from by placing it at the top of the list. Following this adjustment, ensure the boot order is accurate, and the first boot drive contains complete startup files and set it as the primary boot device.

Step 4. Once you have verified all settings are correct, proceed to the "Exit" or "Save and Exit" option. Select "Yes" to confirm your exit and save the changes.
