Using Disk2VHD to P2V a Server 2003 Machine

I'm trying to P2V a 2003 server to a Hyper-V 2012 R2 server. I've used Disk2VHD before with no issues. For some reason on this machine after I create the VHDX file and a Virtual machine and try to boot the server I get a 0x00007b blue screen. I don't have SCVMM in the environment, I'm hoping someone can point me to a solution where I can successfully P2V this server.
