Boot sector contains information known as metadata. Metadata is responsible for maintaining a summary of all the contents on the drive. It also keeps track of any changes made.
So whenever the metadata file gets manipulated, first boot sectors will get corrupt or unreadable. Following are the list of conditions that cause an unreadable NTFS boot sector.

If you are facing issues like increased in booting time of a drive, missing random files or, shrink in storage space there is a chance of defective sectors. You can repair bad sectors by using the Check Disk or chkdsk. Check Disk is a Windows utility tool programmed to repair disk related issues on NTFS and FAT drives. Running Check Disk will locate and repair bad sectors to make them reusable.
