Merge disk 0 to disk 1, etc.

To resolve the issue, you can extend the C drive by adding unallocated or free space from the same disk, or increase the system drive size. If there's no available space on the target disk, you can convert the two disks to dynamic disks and merge them into one, effectively resolving the problem.
