It is probably that the system reversed partition is not set to active, so that you get the error issue.

System reserved partition is a partition that you can find before the system partition (normally the C: drive). In general, Windows doesn’t assign a drive letter to this partition, hence you’ll only see it when you open Disk Management or a similar utility.

To set the system reserved partition to active, you can use the built-in DiskPart, which is on many Windows systems.

DiskPart is a disk partitioning utility that uses command lines to perform operations. Using DiskPart commands can help you manage your computer’s drives including disks, partitions, volumes, and virtual hard disks.

You can follow the steps below to troubleshoot the issue via the Command Prompt.
