To help you out, we will be explaining all about it below.
Why the “We Couldn’t Update System Reserved Partition” Error Occurs?
It is a typical error that occurs while updating or upgrading Windows systems. The System Reserved partition holds essential boot files for your System that are required to start your Windows PC correctly. These are two common reasons why System reserved partition may not function as it is intended to:
First, there is a high chance that the System Reserved partition doesn’t have enough space. If it’s too full, you won’t be able to upgrade/update your PC.
