I'm having a strange issue. I have made a test environment to test and learn WDS and MDT 2013 for imaging.
When I create a new VM for Windows 7 64Bit and it boots from PXE I get an 0x000000C4 error. See screen shot and log file.

Here comes the strange part. When I change the VM settings into Windows 8.1 64 Bit version no problem.
Is this maybe a VM hardware error?
