A boot device can be anything, either a USB flash drive, hard disk, floppy drive, CD/DVD, or any other storage media that stores the necessary boot files.
What Causes the Boot Device not Found Error?

How to Fix the Boot Device not Found Error on Windows 11/10?
Let’s discuss a few troubleshooting methods that you can use for getting past this error notification.
1. Run the CHKDSK Command
CHKDSK (Check Disk) command is an effective tool that allows you to scan and fix disk-related errors on Windows. It allows you to fix bad sectors on the disk, repair corrupt system files, and resolve file system errors. To run the CHKDSK command on Windows, follow these quick steps:
Launch the Start menu search box, type “Command Prompt”, right-click on its icon, and select “Run as Administrator”.
In the Command Prompt window, type the following command and hit Enter:
Chkdsk C: /f /r /v
The syntax of the CHKDSK command is pretty simple. The command is followed by the disk drive initial on which you need to perform the scan. /f fixes the disk errors, /r is used for locating the bad sectors on the hard drive, and /v was specified to display each file that has been checked and processed by the CHKDSK tool.
After running the CHKDSK command, reboot your device and check if the issues persist.
