    Code:
    [COLOR=#ff0000]Recovery/transformation command (? for help): c[/COLOR] 
Warning!
This will probably do weird things if you've converted an 
MBR to GPT form and haven't yet saved the GPT! Proceed? (Y/N): n
    Ha! H*ll, it may do weird things anyway!

    You did not convert any MBR to a GPT. It appears you already have a GPT -- or some strange hybrid (but I doubt that).

    I mean, I've done tons of experiments like this, and I can tell you to expect anything. 98% of the time, it's smooth sailing. But that 2% can take your family photos (happened to me once, had to use PhotoRec to recover 90% of them).

    gdisk isn't seeing it, or telling us -- Even if the main header or partition table is damaged, it should either tell us or see the backup copies of these at the end of the disk. But, ... well, it's a crap shoot, for sure. Personally, I would go ahead and do it if I felt I had nothing to lose anyway, do c first and see where that goes. But I'm a little nuts this way about teasing the Booting Devils. Fair warning.

        Partition table holds up to 128 entries
        Again, that kind of message indicates a GPT, a standard GPT. Now, after "v," it sees an unoccupied table?


        t change a partition's type code
        ? ? ? what if it were messed up? causing gdisk to miss it as a GPT?

        I don't know, exactly, what Windows has done here (Windows did this, you didn't create this partitioning). If you are not shy about it, you could ask Rod Smith if he recognizes this seeming paradox, doing so in a brief-est, summary way.

        Or, continue to explore with gdisk, or try to "fix" it (fix what? )with gdisk -- c & b.

          gdisk sees an empty disk, basically -- NO partitions, all space available ?

              Is this a Dell?

              One thing you can try is a google. I messed around a little, and issues do come up with "WINRETOOLS and PBR image."

                    So, are you giving me the green light to
                    recover the partitions in TestDisk, use backup GPT header (rebuilding main, and then load backup partition table from disk (rebuilding main)
                    and then rewrite
                    Well, that's what this deal points at. The google (above) on how Dell/Windows set this up MAY be revealing, but I've only skimmed a couple links (and people do seem to have issues with this, to word it gently ...)

                      ok so disregard Post #80, I see. If you know you have missing partitions, then yes, TesdDisk seems to do very well at recovery, IME.

                        Yes, it is a Dell. I'll look into those. Also, here's what I meant to post in Post 80 (before I finished and put the code in.


                        Shall I continue with the recovery options? Shall I recover the partitions with TestDisk?
                        Did you SEE missing partitions on the TestDisk output, that you know of? If so, then, yes, recover those. I'll look at the output again, but you would be the one to know what is missing. Or, as TestDisk step-by-step says, a duplicate partition is also a clue; or overlapping partitions.
                        Testdisk says I have either ONE partition (Intel map):

                        Code:
                        Current partition structure:     Partition                  Start        End    Size in sectors

                        ...but there are more that it can recover:

                        While Gdisk says there are no partitions:

                        So, is it a good idea to:
                        recover the partitions in TestDisk,
                        use option Gdisk recovery option b to backup GPT header (rebuilding main, and
                        then use gdisk recovery option c to load backup partition table from disk (rebuilding main)?
                        So, shall I recover the partitions using the Intel map, or the EFI GPT map?

                        And, should they all be primary partitions?

                              Change it to this: Use the EFI GPT map showing that list of partitions to recover you posted above.
                              All primary partitions.

                              This can only be a guess, a crap-shoot.
