Trying to PXE boot a Gen 2 VM in Hyper-V

[coonwhiz]

I currently am using Windows deployment services to do imaging and deployment of machines. I created a gen 1 VM to install the OS on, then have a Gen 2 VM pointed at that vhd. Then I should be able to pxe boot the Gen2 VM and capture the image so that I can deploy it to physical machines. But when I go to pxe boot I get an error screen:

pxe-boot using ipv4
....
Station IP is 192.168.11.3
Server IP is 192.168.11.204

NBP filename is boot\x64\wdsmgfw.efi
NBP filesize is 0 Bytes

PXE-23:Client received TFTP error from server.
Boot failed EFI Network
Boot failed EFI SCSI Device.
No OS was loaded.

I have looked all over, trying to figure this out. Suggestions would be great!

 

EDIT: also I am trying to capture an x86 operating system if that helps

Does it work with gen 1/ hardware?

 

Is secure boot on?

Secure boot is on, but I have tried turning it off as well.

 

Just tried gen1 and it looks like it was able to pxe boot just fine

Any specific reason your wanting Gen2?

ATM there isn't really a point for general purpose stuff (read 99% of deployments). Also assuming your using MDT, just use the USB instead of PXE till you have the process down.

I am a student lab assistant trying to design a lab manual for a computer networking/administration course in college. The lab manual that the professor wrote, and I am testing, timing and adding screenshots to, says to use a Gen 2 VM. So that's what I did. The first time it worked without issue, so I ran through the lab again months later and now it wouldn't work no matter what I did. After switching to Gen 1 it seems to work perfectly so I went to ask the professor why he wanted to use a Gen 2. He said there was no real reason, just that he knew gen 2 should be able to pxe boot and wanted to give the students a chance to pxe boot. He either didn't know that Gen1 could pxe boot, or just saw that gen 2 could before he saw that gen 1 also could.
