WDS and UEFI Boot

[mball212358]

Hello all,

I'm new to the forum, but have been using iPXE in my lab for a while for a gambit of things.

I just ran into something that is fairly strange and hoping you guys have seen this before or can point me in the right direction.

I am using WDS/DHCP servers to deploy some new HP laptops.

Seems I can do one at a time, but when I try to do a second one simultaneously, I'm getting the following:

Registered SAN Device 0x80
Booting from SAN Device 0x80

And then it hangs and eventually goes back to the BIOS boot menu.

In the ipxe menu file, I have the following:

:install-win10
sanboot http://x.y.z.a/wds.iso

Loading into the iPXE menu is fine, just hanges after making the selection.

Any ideas??

Thanks in advance.
