How to recover Win7 partition table loss?

The steps are as follows:

I decided to try the Bootrec.exe repair tool that comes with Win7 to fix the partition table

First, let's briefly introduce Bootrec.exe, here we will use The system partition to the two parameters /fixmbr and /fixboot, /FixMbr option is written to Win7 or Win Vista compatible MBR, this option will not overwrite the existing partition table. The /FixBoot option writes a new boot sector to the system partition by using a boot sector with Win Vista or Win7. Detailed instructions we can view the official Microsoft introduction.

Use the U disk or CD-ROM drive to enter the Win7 installation interface, press shift+f10 to enter the command prompt interface:

Enter bootrce.exe /fixmbr or bootrce.exe /fixboot to try to repair, often The above attempt, my hard disk partition table did not return to normal. If everyone's has not returned to normal, please see below.

Second, use DiskGenius to restore the partition table

1, after using Booterc.exe to repair the partition table failed, I downloaded DiskGenius to try, first on another computer Copy the downloaded DiskGenius into the U disk, then just find an XP installation disk, PE system, copy DiskGenius into the PE system, and then click Tools & mdash; search for the lost partition (rebuild partition table).

2. The search scope is set to the entire hard disk.

3, after starting the search, DiskGenius will display the next hard disk partition one by one. At this time, you need to judge whether the searched partition is your lost partition. If yes, click to save.

4, if the search is completed, if you have completely retrieved the original partition, click on the hard disk & mdash; save the partition table, restart the computer into the PE, you will find that the original hard drive has been restored to its original appearance. If you think that I am not detailed enough, you can also look at the help of DiskGenius's official website.

5, after a night of toss, although the lost hard disk partition has been recovered, but still let people have a cold sweat.

6, after this thing, I summed up two experiences:

First, the hard disk partition table is not killed.

Second, important information must be carved into a CD to save.
