Causes of “Invalid partition table”

A partition table is a table that the operating system keeps on the disk to describe the partitions on the disk. This term is most frequently related to the MBR (Master Boot Record) partition table of a MBR in IBM PC compatibles, but it can also refer to other partitioning "formats" as well.

The system cannot find the partition from which to boot if the partition table is damaged or corrupt, and the boot process will stop as a result. The common reasons for partition table corruption are as follows.

♦Partition table is damaged. A corrupted hard drive or a failed disk write will harm the partition table. The damaged partition table can be found in the boot sector's MBR, which contains data on how the logical partitions, containing file systems, are set up on that medium.
♦Two partitions are marked as active. Only one partition on the hard disk should be marked as active in order to designate it as the one from which to boot. The process of loading the operating system is stopped if the MBR finds two active partitions on the disk at hand. This is typically brought on by mistakes made when manually arranging the partitions.
♦Others. Virus attacks, unexpected shutdown, human error, etc.

Whatever the circumstance is, we'll show you how to recover partition table in the following section.
