For the most part it is a partition of some kind. You'd have to use a tool that would tell you the partition number or better yet one that can change it.
Then you'd have to image it with dd or cat or partimage or whatever to most likely a very exact partition. Not only would the partition size need to be exact but it's placement. Not always but to be sure I would place it on the same block.as the old on.
Then might need to copy the mbr and view it to see if the F10 is part of the deal. Now this gets kind of complex. You'd need to look at the full boot loader for code.
The change the partition type back to what it was originally.
Even then it may or may not work.
SHORT way, maybe.
Use partimage or other partition copy software to copy the partition and then change the partition number to what it was.
