It definitely sounds like permissions issues. What you'll need to do is take a look at both
the permissions allowed as well as
the ownership of the partitions you carried over.
Check out Sharing and Permissions
and possibly Take Ownership Shortcut
(to make it easier on you). DO NOT TAKE OWNERSHIP OF C:
- you'll effectively defeat the restrictions set by the OS on Program Files and other protected resources, making your computer more vulnerable to attack. The same applies for any system created folders on other drives.
IOW, when you need to use take ownership or adjust the permissions, be sure to do it on a folder by folder basis - just about every physical drive or partition will have a System Restore folder as well as a recycle bin folder that you should not take ownership of nor adjust permissions for - so, trying to save time and doing these tasks for the whole drive may, in effect, render those folders useless to Windows.
