Hyper V VM from VHD Fails

Greetings,

My problem arises from taking a VHD created from Disk2vhd to Hyper V from Server 2012 R2 fails/blue-screens once it is started. The setup is pretty basic Generation1 VM that has an IDE controller. At first I thought the image might be corrupted in some way, but I have an exact copy running on Virutalbox. I simply create a new VM in Virtualbox and select the VHD. From there the VM is started and it boots perfectly and is currently running as I type. On my Server 2012, It boots, fails, then attempts to restore, but cannot due to not having a copy of Server 2008 R2 readily available. My question is:

1. Virtualbox uses a SATA controller and works, Do I need that kind of a setup?
2. Why won't the IDE Controller boot my VHD?
3. I've also tried converting it to a VHDX and the SCSI controller, but why did that fail?
4. Solutions?

I'll confess I'm fairly new to the Hyper V world, and I really need some guidance.
