Windows cannot access Local Disk (C:)

[thedst11]

I was tinkering with the security settings of Local Disk (C: ) so that I get full access to it so as to delete unwanted files. I tried but accidentally now the local disk doesn't have an owner. So I can't access Administrator (cmd). When I try and access those settings to define an owner, it shows 'Access is denied.'. I tried working in safe mode but safe mode won't open. I tried resetting windows 10 both ways (keeping and deleting all files) but it says 'resetting failed.'. I cannot access Local disk (C: ) and cannot opens programs related to it like notepad, task manager, etc. Please help.

Oops - reinstallation time coming up unless you can get to System Restore and make it work.
