How to make my primary drive GPT1 and my second drive GPT2

  1. #11


    Yeah, i guess its probable that if second HDD was MBR, I would not have this problem...
    I'm not interested in starting all over though so I guess I'll have to live with it.

    Wise decision, I'm sure you'll get used to that arrangement in no time. Look at it from the bright side, with GPT on second drive you'd be able to install another OS with UEFI , Win9 is coming soon.

    Actualy you can convert a Logical drive to from GPT to MBR UEFI will recognize it. It is only primary drive with an OS on them that can not be converted.

    And how would I do that? Within Windows DIsk Management? Would this lead to a loss of data on the drive?

    On further research I guess you can change a MBR to GPT but not the other way around So I spoke wrong.

    Does anyone know how to change this assignment so that the SSD will be GPT1 again?
    I know exactly what you mean orlando1974.

    I recently installed an SSD to my machine, and in Macrium, the top line is of course ''GPT 1'' but it pertains to my original HDD>which is now purely a storage drive - the annoying thing is, I was able to delete all the original partitions off it that Windows 8.1 had set, aside from some anonymous 128MB ''unformatted partition'' - it's some sort of Windows partition of course. Due to this, Macrium assumed that HDD also needed to be backed up, as it had a System partition on it.

    The good news is that in their newest update which was literally only released, the software can ascertain the correct bootable disk (in our case, the SSD) and if you select the task ''Create an image of the partitions required to backup and restore Windows'' it selects GPT disk 2 which is correct again in this scenario.

    I however understand that you want to have full control over how you use the software, I don't have an answer to your original question though sorry. I'm sure we'll be careful enough not to be careless when selecting the appropriate backups

    I'm actually on the Pro version myself but would assume that as long as you're running 5.3.7086 then the same should apply, as you might guess! Here is the release notes in case you're interested -

    I was referring in particular to the fix that says ''
    • 'Backup Windows' will now only include the actual boot disk in a UEFI booting systems where multiple EFI system partitions exist.
      Multiple GPT disks with multiple EFI system partitions would cause incorrect selection of non-booting disks. This has been resolved.'

      Again, know it doesn't really resolve your query..

    Well at this point I dont really need to know why my GPT 0 got bumped to GPT 1. I know many others have reported the same so its not like its only me. What matters more is that Macrium fixed the issue so now I wont have to worry about not selecting the right GPT Disk! (hopefully the fix will work for me!).

    So thanks again rowlands. Your solution was good enough to solve this thread.
