Delete Win 7 OS files from Win 10l

Motherboard failed. New MB wouldn't boot old HD. Installed Win 10 on SSD. Can't delete Win 7 files from HD: owned by TrustedInstaller. Don't want to reformat.

That worked. What I missed was that the user or group (in my case "Administrators") needed to be entered in the "Enter the object names to select" field of the "select Users or Groups" dialog box.
Thank you.
Resolved.
