Wrong boot sequence: If you haven't changed the boot order after migrating your system to a new hard disk, your BIOS Boot Sequence can't locate the new bootable disk, which leads to the unbootable hard drive.

Damaged hard drive: A damaged hard drive, with logical issues or physical corruption, can cause the system not to boot. This is a situation that needs to be taken to a professional repair facility. In order to avoid data loss that this kind of reason may cause, it is recommended that you back up the data regularly.

Bad sectors or corrupted boot files: If there is a bad sector on your hard drive or a virus that get into the disk and corrupts the boot file, you will also encounter the hard drive won't boot

Undone OS update: When you do not update the driver of your hard disk in time, you may also have the problem that the hard disk can not be booted. In this case, you just need to update the driver of your hard disk to the latest version.
