[5 Steps] Fix "We Couldn't Update the System Reserved Partition"
About "We couldn't update the system reserved partition"
When upgrading to Windows 10 from Windows 8.1 or Windows 7, the upgrade may fail with an error message saying "We couldn't update the system reserved partition" along with error codes like 0x800F0922 or others.
Why is it unable to update system reserved partition?
The Windows 10 upgrade error is typically caused by insufficient space on the system reserved partition. When Windows is installed to a partitioned MBR disk, an additional partition is created without a drive letter, labeled as system reserved, which stores important boot files and is usually located before the system partition (often known as C: drive).
On Windows 7, it takes 100MB, 350MB on Windows 8, and 500MB on Windows 10, with Windows 10 requiring enough space on the system reserved partition for a successful upgrade.
If you freshly install Windows 10 to a specific partition, you won't encounter this error. The system reserved partition, which first appeared in Windows 7, is the reason for this issue, so you won't experience it on earlier versions of Windows.
