I don't have a UEFI based computer so I can't explain from experience but I believe Paragon should be able to convert the disk to GPT and then clone the OS using the full drive.

    Or you could clone again giving the 750gb unallocated and then convert the drive making the 750gb available. I know Partition Wizard and Easeus free partition manager versions can convert between MBR/GPT disks without data loss and Paragon should be able to do the same.

    I followed the advice in this thread: 3TB now 2TB. How do I get my 3TB Back? - Seagate Community Forums

    I formatted the 3TB drive in GBT too but in Paragon when it transfers the OS it'll still create a 750GB unallocated partition.

    Do you have a UEFI/BIOS firmware motherboard?

    I would get away from Mint and go to the latest versions of Ubuntu. It will install as Legacy or UEFI and even be compatible with the Windows 8 secure Boot. You could then set both drives as GPT and install however you wanted.

    Edit: Or install both OSes as Legacy on the current small drive and leave the 3 TB for data.

    I installed Windows 8 UEFI on my 3TB drive. When I looked in disk management whilst running W8 on the 3TB drive it showed that it formatted correctly. When I went back on my 500GB drive,the 3TB drive just shows as a plain partition again, plus I had some new problems after, such as Firefox not working correctly and having to reset it, and windows 8 type in search feature broke.

    Ok.. I had to run through "Windows Boot Manager" in bios to get to my 3TB W8 OS, I don't even know what that is. (Windows 8 Type-In Search works fine on the 3TB disc by the way)

    This is what my 3TB drive looks like when I'm running that. Click image for larger version
    This is what it looks like on my 500GB drive.Click image for larger version

    Someone please help.. this is getting outside my area of knowledge. Would it just be easier to do a full reformat and manually transfer all my files?

    From my perspective, I am a little confused as to your current situation and where you want to end up.

    Did you install Windows 8 on the 3 TB decided you did not want that because of some errors? Did you just install and re-install your programs, or try to copy old stuff over?

    I of course, would only use around 150 GB for a Windows 8 OS partition, but that might not be relevant right now. Tell us, if you have decided to install Windows 8 on the 3 TB drive, exactly what you are doing to make that happen. Drive letters will show up differently depending on which OS has been booted into. You probably need to remove the small drive until you get your Windows 8 install where you want it.

    I want to migrate my OS to a 3TB drive. I did that with Paragon but I didn't realise that it would leave around 750GB of unallocated space after. After around 2 days of using the 3TB to boot it started having booting problems saying the OS was broken - I thought this was because the System System Reserved partition was still on my 500GB hdd.

    I want to end up where I'll have W8 on my 3TB drive with no unallocated partition and have Linux installed for a dual-boot system on my 500GB drive.

    I followed this: UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with

    As Paragon can't migrate to hdd's over 3TB without creating unallocated partitions I'm now manually just transferring all of my files over from the 500GB drive back to the 3TB drive after doing the UEFI format/install. I didn't want to do this as it's just a major hassle and a last resort if I couldn't find any other solution.
