Why can't I change my drive letters?

Episode 1203 (1:12:14)

Chuck from Telohoma, TN

Chuck recently restored his computer to Windows 7, but he's now having trouble with assigning drive letters. Leo says that Windows always wants to be on the C drive. The partitioner won't let Chuck go beyond D. Leo says that Acronis True Image could do it, as will CloneZilla. The Chatroom suggests going into the disc manager of Windows, then right click "select change drive letter settings."
