Hi Dawwid,
I'm Sumit, here to answer your query at the Microsoft Community.
Apologies for any inconvenience you are experiencing. I am happy to help you today.
I'm not so sure, but I believe the C drive is pointing to the WinRE partition(WinRE is also an OS, but technically, it's a very tiny one), which also runs with its own C drive.
To answer your question:
- Yes, it is perfectly safe to force dismount.
- After this command, ensure to run
chkdsk D: \f
as well. It ensures the actual OS drive is also scanned as well, in case my assumption is true.
I look forward to your response and am eager to collaborate until we find a solution.
