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

I have a laptop that has an SSD with Win 8.1 + programs, and an HDD for projects. They are both formatted GPT. When I launch Macrium, for some reason my SSD is now GPT 1 and the second drive is now GPT 2. This is confusing because I'm used to imaging the top line of partitions which is usually my OS. Now that the GPT numbers are reversed, I have to be careful when doing my backups.

Does anyone know how to change this assignment so that the SSD will be GPT1 again?

I just give them separate names, "System" for first, boot drive, "Data 1", for next and others by names that describe what I'm using them for. That way there is no confusion when some programs or OSs reverse or mix order.

Hmm, this doesnt truly answer my question Count Mike. They already have their own names. I'm talking about some sort of assignment that is done under the hood. In Disk Management, the primary drive was bumped to Disk 1 after I installed the second drive, which took its place as Disk 0.

Is there no way to exchange these assignments?

Update: looks like its a common issue for which there is no definite solution... Disk numbers in Disk Management matters? - Windows 7 Help Forums

Maybe if you changed their places on the SATA ports in MB. It just stands to reason that HDD0 becomes GPT1 and next one GPT 2. It's also logical that BOOT/system drive be first drive /HDD0.

I cannot change their ports... this is a laptop that came with ONE drive. I swapped it out for an SSD and installed Windows 8.1 on it. Once all that was done, I installed a second drive where the optical drive used to be, using an HDD Caddy. This is what bumped the SSD to Disk 1 from Disk 0. So it actually looks at where my optical drive used to be as Disk 0! Hmmm...

Anything in BIOS that can turn things around. I know, laptop BIOSes are not exactly power houses but.....

Not sure where I would look.
Off topic, in going into my American Megatrends bios I did notice that Fast Boot is set to Disabled. I'm already finding the boot is incredibly fast... and this is turned off. I wonder if I should turn it on.. i dont know what it does?

Goes faster thru BIOS, no relation to OS. Starts Booting faster before windows starts to boot. With an SSD really not necessary.

OK thanks.... well original question not solved still, so I'll leave the thread open for a bit. Seems to me there's no solution... seems to have happened to lots of people when they install an SSD alongside other drives. Weird though because I had specifically installed OS prior to connecting second HDD.

You did that part right, why is GPT switching and if on MBR it does not happen ? If you are using GPT because of UEFI Bios, you don't need second HDD to be too, MBR should work on it.

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.

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 ''
  • [FONT=Verdana, Arial, Helvetica, sans-serif]'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..[/FONT]

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. :)
