Thanks for the reply. Both OS's are Windows 7 x64 Home Premium. I was doing some SSD vs HDD benchmarking for work. I'm presuming I installed first to the drive labled "Disk 1" in the screenshot because that's where the EFI System partition is. I actually don't remember, unfortunately.
My assumption is I need to do the following:
- Move/resize the C: partition.
- Copy the EFI System partition to Disk 0.
- "Fix" the bootloader, if it's possible.
- Remove Disk 1.
I tried to use EaseUS Todo Backup because I did something similar on a work machine but it doesn't recognize any of the partitions on these hard drives (it recognizes my data drive and DVD drive; I'm presuming it's because those are MBR and the two drives with OS's on them are GPT).
Appreciate any help you can offer (mainly if you can confirm whether or not DBP can do this, I'm happy to pay for it and figure it out from there).
FWIW, if there's another way to do this that preserves the OS install on Disk 0 I'm ok with it. I.e. can I "clone" the OS, make the partition smaller, add a new boot partition, restore the OS, etc.? I don't need to keep the existing boot partition if I don't have to, I'm just trying to avoid a full OS re-install.
