Solution to prompt invalid partition table after reloading Win7 flagship system

Cause analysis: Typically, there is an error in the partition table in the master boot record of the hard disk. This failure occurs when more than one bootstrap partition is specified (only one bootstrap partition) or the virus occupies the partition table, and the Master Boot Record (MBR) is located in 0 heads/0 cylinders/1 sectors. Generated by FDISK.EXE on the hard disk partition, MBR includes main bootstrapper, partition table and end flag 55AAH three parts, a total of a sector, the main boot program contains check the hard disk partition table program code and error information, error handling and so on.

When the hard disk is started, the master bootstrapper checks the bootstrap flag in the partition table. If a partition is a bootstrap partition, then there is a partition mark 80H, or 00H, and the system requires only one partition as a bootstrap partition, so if the partition table contains multiple bootstrap flags, the main bootstrapper will give "Invalid partion table" error prompts.
