Then, TestDisk will be successful completion but restoration is not done.

*Microsoft names boot sector only PBR.Īs long as checking on the screen, since backup boot sector became 'Status: OK', it seems to be able to restore if write it into PBR.Īs a note of caution, if PBR is incorrect, TestDisk sometimes consider it to be 'Status: OK'. Here, I will provide an additional explanation about how to read the screen.Īdditionally, the term boot sector here is PBR. If it is clear that PBR is corrupt and it is recognized by TestDisk, sometimes happens that this screen will be displayed automatically when choosing 'Write' after 'Analyse'.Īccording to the example image above, boot sector is 'Status: Bad' meaning is corrupt and backup boot sector is 'Status: OK' - they show that both sides are not identical.īackup boot sector is really the copy of PBR and in the case of NTFS partition, they exist at last sector of each partition. On the other hand, in this page, I will explain about the partition cannot restore only by reparing partition table.įirst, choose 'Advanced' at main menu of TestDisk.Ĭontinuously, choose the restoration partition with using up/down arrow keys, then choose 'Boot'.įrom here, you can operate about PBR of the partition you choose. It is written about how to get it and basic operation procedure.īut this is compiled about reparing partition table mainly. I will pursue the subject that you understand the following page in the premise. PC can recognize the partition only after both sectors become normal condition. There are two main types of boot sectors - One is MBR (Master Boot Record) which is top of the disk and the other is PBR (Partition Boot Record) which is top of the partition. The information regarding partitions are not written somewhere file.īasically, they are written in the one sector called 'boot sector'. Two important sectors for recovering the partition Therefore, repairing PBR often becomes hard work but TestDisk can achieve it easier.

If PBR has some troubles, OS cannot access to this partition.Īnd also if it is an active partition, Windows will not be able to boot. It is not only MBR but also can repair PBR. TestDisk is an exceptional tool for reparing boot sector.
