That happens if you try to access system directories created by another Windows installation.

To access the files, you need to CLAIM OWNERSHIP. In short: go to folder settings (in the menu of explorer somewhere; not iexplorer but explorer). There's a setting for simple file sharing, disable it!

Then, right click the directory you want access to, and it should have a Security tab. Open it and choose to claim ownership, including all subdirectories (inherited).

Good luck!
