No Bootable Device: How to solve this problem

Introduction:
"no bootable device" is an error message that appears during the computer startup process. This usually means that the computer cannot find a device, such as a hard drive or SSD, that can be used to boot the system. This article will describe several possible causes and ways to resolve this issue.

Possible causes:

1. Corrupted hard drive: A damaged hard drive may cause the computer to be unable to read system files, resulting in a No Bootable Device error.
2. BIOS setting error: BIOS is the computer boot program. If the BIOS setting is incorrect, the computer will not be able to boot the device correctly.
3. Corrupted operating system: Corrupted operating system files may prevent the computer from starting properly.

Solution:
Note: Before trying the following solutions, it is recommended to back up your important data to avoid loss.

1. Check the hard drive connection:
   Make sure the hard drive and data/power cable are properly connected. Turn off the computer, unplug the data and power cables from the hard drive slot, and then plug them back in. Restart your computer and see if the problem is resolved.
2. Check the BIOS settings:
   Enter the computer's BIOS setting interface (usually press the DEL, F2, F10 or ESC key to enter when booting). In the BIOS settings, make sure the hard drive device is higher in the "Boot Order". If you get any errors regarding startup settings, look on the Internet for guidance on the correct settings for your computer make and model.
3. Use a boot repair tool:
   If your computer has a preinstalled operating system, you can try using the operating system's boot repair tool. For example, for Windows operating systems, you can use the "Repair your PC" option. Insert the operating system installation media (such as a USB or disc) into your computer, restart and follow the on-screen instructions.
4. Use troubleshooting tools:
   You can try using troubleshooting tools to diagnose and repair hard drive problems. For example, use Windows’ command prompt tool to run the “chkdsk” command to scan and fix errors on your hard drive. In addition, you can also use the disk utility provided by the operating system to check the health status of the hard disk.
5. Reinstall the operating system:
   If none of the above methods work, you may need to reinstall the operating system. Make sure you have legitimate operating system installation media and license keys. Before reinstalling the operating system, make sure you have backed up your important data.

Conclusion:
The "no bootable device" error is usually caused by a failed hard drive, incorrect BIOS settings, or a damaged operating system. You can resolve this issue by checking the hard drive connection, adjusting BIOS settings, using a boot repair tool, running a troubleshooting tool, or reinstalling the operating system. If none of the above methods work, it is recommended to seek help from a computer repair professional. Remember, before trying any solution, always back up your important data to avoid losing it.
