I know this isn't a question that's specific to Unix/Linux, but I think there are people who can answer this question here.
I want to hide my Windows partition from the partition table completely, then later I want it to come back. I'm sure it's something simple to do, but it's safer to ask people who know instead of fiddling with the partition table myself and mistakenly lose my data.
By "hide" I mean I want that area of the disk to appear unallocated. Basically remove the "partition entry" if that makes sense without removing the data itself, so later I can just change the partition table again to make it have a partition entry at the exact location, so I can access it again.
