I downloaded an MS update on my machine and it totally wiped the hard drive. I had to call support and get a new copy of windows 10. I reinstall windows 10 and everything seems all good until I try to install on my partition. I have a 1tb drive partitioned 150g (C)for windows install 750g(D) for programs. Now it’s saying I don’t have permission to install or edit files on my D: drive. My user name is the administrator on the PC and I don’t see any other users. It’s a fresh wipe so I don’t have any malware. I’m not sure what to do any advice?
