The “No boot disk has been detected or the disk has failed” error usually appears when the user attempts to boot the computer. It usually indicates that the boot configuration is incorrect or the boot diskette is damaged.
The “No boot disk has been detected or the disk has failed” error can have several reasons, including the following
The connection of the hard drive to the system is faulty or failed which is silly, I know, but it happens sometimes.
- Your system’s hard drive is down
- The start sequence is not set correctly.
- The operating system on the hard drive is missing.
- The BCD (boot configuration data) is damaged.
Check Computer Boot Order
In addition, an incorrect startup sequence on the computer may also cause this error. Therefore, you should check the startup sequence.
- Reboot your computer first and, in the meantime, press the “Clear” or “F1” or “F2” key to access the BIOS setup screen.
- Then switch to the “BIOS” tab in the above list of options.
- Next, you can check the boot device priority to determine if the computer’s hard drive has the highest priority. If not, change the order.
- Finally, press “F10” to save the changes and complete the BIOS setup.
Checking the connections between the PC and the hard disk drive
Sometimes the laptop may wobble, causing the PC-HDD connections to loosen.
The wires connecting the hard disk drive to the system and vice versa may have become loose, resulting in the error message “No boot disk has been detected or the disk has failed”.

Run startup diagnostics to see if the hard disk drive has failed.
If the above two methods are not helpful at all, there is a risk that your hard disk drive may be damaged or corrupted. In either case, you will need to replace your current hard drive or SSD with a new one and reinstall Windows. However, before drawing a conclusion, you should run Windows diagnostics to check whether you really need to replace your hard drive/SSD.
To run the diagnostics, reboot your PC, and while the computer is booting (in front of the boot screen), press F12, and when the Boot Menu appears, highlight the Boot to Utility Partition option or the Diagnostics option and press Enter to run the diagnostics. This will automatically check all the hardware in your system and generate a report if a problem occurs.
Clean Install Windows
If the above methods do not work, it means that the computer’s boot disk did not fail, but the operating system or boot information that was on the boot diskette can be erased. If this happens, the best solution is to reinstall Windows from scratch. However, be aware that reinstalling Windows could result in data loss.
If you have lost data after reinstalling Windows, you can use this Windows Recovery Tool to restore your files. It can recover data from undetectable hard disks, inaccessible disks, formatted disks, etc. In addition, you can easily recover files from damaged, corrupted or reformatted partitions.
