I am trying to set up my 2nd partition for a 700GB HD. I'm using the first 200 GB for the OS and want the second partition to utilize the remaining space. Currently I can only create a partition of 265 GB. I've done research in the past on this and found a guide that requires editing a file in the hkeylocalmachine/x/x/x path but my terminology for google searches is only finding people posting about the misrepresentation of actual HD size vs what is claimed by the manufacturer. Would anyone mind providing a link to a guide on how to edit this data or create a guide as a response so that I can get my system complete? Thanks in advance!
