Many users who use Windows 7 have found a 100M hidden partition in their hard drive. What does the partition do?
100M hidden partition
Look at Microsoft's official explanation:
The main reasons for creating this partition:
1.Bitlocker requires that the Boot files and Windows files be separated. (BitLocker stipulates that boot files and Windows files should be separated.)
Also, this system partition may be used by utility software, such as backup problems, to support dualboot scenarios. This system partition can use utility software, such as backup, to support dual boot.)
2. Protect against deletion.
If files saved on system partition, it is easy to lose the boot files Due to a format when reinstalling the operation system on system partition. (If the startup file is saved in the system partition, it is easy to format and lose these startup files because of the reloading activity on the system partition)
The drive received no drive letter As further protection against accidental deletion of the boot files. (The drive does not have a drive letter to prevent accidental deletion of the boot. Pieces.)

Okay, I admit that Microsoft has his reasons, but look at the complaints that are now in the world, you know this 100M The partition obviously has a lot of disadvantages.
The notebook has just been shipped, or you created the partition with the installation file when you installed WIN7, then it will have this 100M hidden partition. He brought us the following disadvantages:
1, can not use the GHOST version of the system CD to install WIN7, can only use the installation version to install step by step.
2. After installing the system, you cannot use the one-key restore software such as Wingho and OneKey Ghost to back up the system.
3, Norton Partition Magic can not be used normally, if you try to repair this 100MB partition, it will cause the installed WIN7 can not boot.
4, WIN7 activation with 100MB partition is very troublesome, always unsuccessful.
PM can't operate on the partition
The problem that GHOST can't be used normally is probably the most touching user. Because using GHOST backup system, has become the habit of many users, with Microsoft's own backup tool, I am afraid it will cause everyone's dissatisfaction.
In addition, the fourth article is also a point that many users hate.
Summary, this 100M partition is mainly for everyone to bring the trouble is, disk partitioning, system backup and other common skills, you have not learned the set, you have to learn a new set of Microsoft recommended, and There is no performance improvement.
If you have not installed WIN7, remember to use the tools such as PM to pre-divide the partitions in advance before installing. Do not involve the operation of creating new partitions when installing WIN7, you can avoid the generation of this 100M partition.
