What Is System Reserved Partition?
When you choose unallocated space to install a fresh new Windows operating system or Windows Server, a System Reserved Partition (SRP) is created. This partition stores the Boot Manager Code, the Boot Configuration Database, and the startup files needed for BitLocker Drive Encryption.

The Windows Boot Manager recognizes the boot data from the Boot Configuration Data Store whenever the computer boots. The boot loader is launched by your system from the System Reserved partition, which starts Windows from the system drive. If you use BitLocker drive encryption to encode your hard drive, the System Reserved partition contains all the files needed to boot your computer properly.
Your system boots from the unencrypted System Reserved Partition before decrypting the main encrypted drive and booting the encrypted Windows system.
System Reserved Partition sizes vary depending on the operating system.
OS Versions |
SRP Size |
Windows 7 |
100MB |
Windows 8/8.1 |
350MB |
Windows 10 |
500MB |
Windows 11 |
500MB |
Can I Delete the System Reserved Partition?
Removing the System Reserved Partition is technically possible, but you shouldn't do that because it will almost certainly break your system. As previously stated, Windows stores your critical boot files on the System Reserved Partition.
