What Does It Mean If Your Computer Gives an Error Message Stating No Bootable Device Found

My computer encounters BSOD with a message saying 'Inaccessible Boot Device,' and then I restart it only to find another message showing 'No Bootable Device Found.' I have tried a few methods, but nothing truly fixes the error. I even reinstalled the system, but when I updated Windows, my computer restarted, and the error occurred again. What does 'No Bootable Device Found' mean, and how do I fix this? Appreciate for any help!

"No Bootable Device Found" means the system cannot locate an available bootable disk. The issue could be caused by various reasons, such as disk connection issues, misconfigured BIOS settings like incorrect boot order, corrupted disk, damaged system files, etc.

In order to fix the error, you can first enter the BIOS and see if the boot order is configured correctly.

Step 1. Restart your computer and press "Del," "F2," "F10," or other BIOS hotkey to access BIOS.

Step 2. Go to the "Boot" tab and set your system hard drive as the first one in the boot order list.

If this helps you resolve the problem, congratulations! If not, try a professional boot repair tool - EaseUS Partition Master Professional.

It provides a powerful feature with an advanced algorithm that can detect corrupted system files and repair them automatically. If the error occurs due to damaged system files like BCD, this tool can help you.
