Fix: Unable to update system reserved partition in Windows 11
Reasons for this error
Let's get down to the basics first. Here, the denmark telegram data System Reserved Partition SRP is a small partition on your Windows installation that doesn't have a drive letter assigned and is hidden . Basically, it does two things:
Boot Manager and Boot Configuration Data: When you start your computer, the Windows Boot Manager reads the boot data from the Boot Configuration Data BCD store. This helps you start Windows.
BitLocker Drive Encryption: When you decide to enable BitLocker Drive Encryption, the SRP plays an important role. BitLocker writes data to the SRP that helps you start an encrypted Windows installation.
This error may occur when the SRP is full or has no free space. Some third-party applications may write to the SRP and fill it up. Once full, and when performing an update or installation, a header error may occur.
To resolve this issue, you need to free up at least 15 MB if you are installing. And if you are upgrading, free up at least 13 MB on SRP.
