That's what I thought, the 2TB was not supported.
I converted a test system over, increasing to 1TB.
After a successful conversion, I edited the VM settings and increased the hard drive to 2TB.
Booted into GParted ISO and modified the partition to 2TB.
Rebooted Windows, chkdsk performed a scan.
Rebooted 2nd time back into Windows.
Verified I have a 2TB drive.
In essence, I didn't even have to increase to 1TB during the conversion, I could have left it as it was and just modified after like I did.
Thank you for your comments and direction.
