How to remove 100MB of space automatically generated by Windows 7

I heard that Windows
7 will automatically generate 100MB space after installation, if it will cause the hard disk partition table error. Today we will solve the problem of deleting the hard disk partition table after removing 100MB. Anyway, my hard drive is big, not deleted. It is not recommended that you delete it, because it is a backup function that comes with WIN7. It will be introduced below. If you delete it will cause an error. If a friend does not know to delete this 100MB partition by mistake. Please use the following methods to save your hard drive. We can use the DiskPart tool to clear the wrong partition list and then re-partition the hard disk, the above problem can be fixed. With Windows 7 or Vista's System Recovery Tool (WinPE 2.0), select the “Command Prompt” option and enter the command. It should be noted here that before doing this, you need to back up important data files on the hard disk to other hard disks. Now, using Norton Partition Magic to view and partition the hard drive, the error no longer exists. When you experience Windows 7, you don't have to panic about some seemingly new features or their impact. For example, the 100MB partition mentioned in this article actually exists in the Windows Vista era according to different user needs, if you don't delete it. The partition will not have any effect. Its attribute is the active partition. In the future, installing the OS
boot file on the hard disk will be automatically written into the partition. For future, if you need to install Windows 7 on a brand new or unpartitioned hard drive, I recommend accepting a hard drive layout with a 100MB partition. Understand the reason for this 100MB.
Windows 7 will store the system boot file and WinRE in the partition and hide this partition. The purpose is not only to protect the system boot partition, but also for the need to use For users of Bitlocker drive encryption, there is no need to redeploy the hard drive structure in the future. For the sake of the following, it is necessary to briefly introduce the requirements of the Bitlocker drive encryption for the hard disk layout. Simply put, “Bitlocker Drive Encryption” is not able to encrypt the boot file when encrypting the hard drive data. If the boot file is encrypted, it will obviously cause the system to fail. In Windows Vista, if users need to use the "Bitlocker Drive Encryption" function, they must create an additional partition for the system boot file (not the partition where the system files are located and other partitions that need to be encrypted). This partition for storing system boot files is not very difficult for an unpartitioned hard drive. It only needs to be deployed using the DsikPart tool or with other third-party tools; but for a hard drive with multiple partitions installed and with multiple partitions How to move the system boot file to a dedicated partition? If you have a good understanding of Windows Vista before, then you must know "Bitlocker driver preparation tool". With this tool, you can create an active partition that stores the system boot files later in the system installation. Through the above introduction, you must have already understood that this additional active partition is not a Windows 7 patent. The partitioning layout of the Windows 7 installer for unpartitioned hard drives is also more convenient for users who may use the "Bitlocker Drive Encryption" function in the future. The above is the introduction of the 100MB partition created by Windows 7. The advantage is that it can better protect the system boot files, store WinRE, and make it easier for users who use the “Bitlocker Drive Encryption” function to directly obtain the required hard disk layout. How to avoid the 100MB partition that appears during installation?
When installing win7 to choose which partition to install, you can't choose unallocated diskspace, or you can choose delete existing partition (for example, C drive). Security: Format Format the existing partitions and install them again. Students who don't like formatting can choose a partition that has already been installed.
