What is the use of reserved partition in win10 system?

The role of the reserved partition in win10 system: The reserved partition is used to store startup files and is reserved for BitLocker drive encryption. This not only saves time in setting up the BitLocker drive, but also reduces the time for users to test in the future. Also available: the status of hidden partitions, the contents of hidden partitions, the impact on system startup after adding hidden partitions, etc.

The system reserved partition refers to the partition reserved for storing system boot files when the Windows system manages the hard disk for the first time.

For security reasons in Windows Vista/7, during the new installation of Windows 7 (and later versions), if you use the CD-ROM partition tool to partition the hard disk, the system will default to a part (100- 200M) space is divided.

Does not assign a drive letter (the letters you see under the system such as C, D, E...), used to store system boot files (the part that needs to be read first when the computer starts) special function files).

The role of the windows system reserved partition:

The reserved partition is used to store startup files and is reserved for BitLocker drive encryption, which not only saves the time of setting up the BitLocker drive time while reducing the time users have to test later.

1. The status of the hidden partition

The format of this partition is NTFS, there is no disk volume label and no drive letter assigned. Its disk status is described as: system, active, primary partition . Because there is no drive letter, it is not visible in Explorer.

2. Hide the contents of the partition

The operation method is: select the partition in Disk Manager, right-click and select "Change Drive Letter and Path" to pop up the change wizard. Click the "Add" button and select "Assign the following drive letter" in the pop-up dialog box, then click on the drop-down list to select F from it, and finally "OK" to exit. Next, open "Computer" and you will see a new disk partition F. Entering this partition, you will find two hidden directories, Boot and System Volume Information, and two hidden files, bootmgr and BOOTSECT.BAK. There is no doubt that Windows 7 saves the system's boot files in this hidden partition.

3. The impact on system startup after adding a hidden partition

Next, we restart the system to see if the above operations will affect the startup of Windows 7. The test results show that the system starts normally. It can be seen that the above modifications will not affect the system startup. The operation of reassigning a drive letter to the boot partition does not modify the system's boot file, nor does it modify the disk boot sector. It can be seen that the reason why Microsoft placed the Windows 7 boot file in a separate hidden partition must be to protect the boot file.

4. The impact of deleting hidden partitions on system startup

Through Disk Manager, trying to "format" and "delete volume" failed. It can be seen that Windows 7 protects this partition. Very well done. Since system tools don't work, try third-party tools. The author used Acronis Disk Director Suite 10.0 for testing, used this tool to delete the partition and the data on it, and then restarted the system. "BOOTMBR is missing" is displayed, which means the master boot sector is missing and the system cannot start. It can be seen that the system's boot file and the disk's primary boot partition information are stored in this hidden partition.

5. The impact of deleting files in hidden partitions on system startup

Log in to the system as administrator, enter the F partition and delete the files. During the deletion process, it was discovered that some of the files could not be deleted, and the message "File in use" or "No permission to delete" was displayed. Then I tried to grant "Full Control Permission" to the administrator, but the result was rejected. After testing, it was found that even system does not have full control permissions. Only the TrusterInstaller user has full control permissions. Restart the system and the system starts normally. It can be seen that the files we just deleted have nothing to do with system startup, but files that are actually related to system startup cannot be deleted.
