Active partition

Active partition is boot partition of computer and boot files of operating system are installed in this partition and it is considered as Disk C in Windows. And in Linux, it depends on specific setting. When system is started, the system in active partition will execute a program named drive mirror, and it distributes drive names to primary partition and logical drive. All primary partitions are mirrored firstly, and the logical drives are appointed with subsequent letters.
When the active partition is damaged, or the original active partition is modified unintentionally (virus or human factors), the operating system can not be started normally. In this occasion, data in current disk is not lost or damaged. All of these are caused by the failure of one active partition, and it is not real meaning of data loss or system damaged seriously. At this time, users need not to worry. And re-installation of operating system or backup recovery software or data recovery software is not needed. What users should do is to recheck boot partition and reset boot partition, and it will work again.
