Quickly Fix Windows couldn’t update system reserved partition

 
Case 1. Extend System Reserved Partition
 
If it is the low disk space that leads to “we couldn’t update system reserved partition”, we need to increase system reserved partition size. (Note that low disk space in EFI system partition can also bring this trouble, but the solution is just the same.)
 
First of all, we need to find out which partition is the system reserved partition. Please pay attention to partition status. The one marked with Active is the right one we are looking for. Usually, system reserved partition is followed by the system partition or other partitions, making it impossible to increase partition size in Disk Management. Hence, we recommend using MiniTool Partition Wizard to help you.
 
Tip: to ensure that the system is OK after extending partition, it is better for you to do it under WinPE. Please follow the guide below to create a bootable media and then boot your PC from it. You can also use the Free Edition, but do it at your own risk.

When you see the main interface of MiniTool Partition Wizard, select the system reserved partition and choose Extend Partition from the action panel. Choose a partition to take some free space from. Click OK to go back to the main interface and hit Apply.
 
Tip: on GPT disk, if there is an “Other” partition located in between the EFI system partition and the partition you want to take some free space from, you can delete the Other partition and the make the extension.

Case 2. Fix file system
 
If there is enough disk space on the system reserved partition, you may consider the file system errors. Luckily, MiniTool Partition Wizard Free Edition offers the way to fix this issue which is called “Check File System”. But first of all, you need to add a drive letter to the system reserved partition, because this feature only works with partitions that have a drive letter.
 
Next, select the system reserved partition and choose “Check File System”. In the pop-up window, tick “check & fix detected errors” and click Start.
 
When you have finished checking and fixing file system, you should remove the drive letter you just added by selecting “Change Letter” again.
