Deleting system reserved partition won't clean up much space because it takes up so little space. On the contrary, because the system boot file is stored on the system reserved partition, deleting it may affect the normal startup of your computer.

What is the System Reserved partition in Windows 11/10?

The system reserved partition refers to the partition reserved for storing system boot files or Windows startup files when the Windows system manages the hard disk for the first time. For security reasons, during the installation of Windows 7 (and later versions), if the hard disk is partitioned by the partition tool of the CD, the system will divide a part of the space (100-200M) by default. No drive letter is used to store system boot files (part of files with special functions that need to be read first when the computer starts).

How do I fix system reserved partition Windows 11/10?

The simplest way to recreate or repair system reserved partition in Windows 11/10 is by using specialized partition manager software, such as EaseUS Partition Master.
