I have partitions set up for multiple Boot. I had it set up to 'hide' the other OS partitions. When I access drive manager, I am supposed to be able to change/delete drive letters. The partitions show up in Explorer with drive letters. In drive manager; they do not show drive letters, so when I get into change drive letter, the remove tab is gray. One thing I did notice in the registry is in the HKEY_Local Machine\system\mounted devices; there is a \mounteddevice1 key also. Is this a glitch in the registry ? I don't get any errors, but if the partition letter shows up in My Computer, it should show up in Drive Manager also. I just want to get rid of the device letters and hide the partitions like before.

Thanks.
