Now were being shipped UEFI machines, and Id rather not have to mess with changing BIOS boot settings each time.

Now, when I PXE boot in UEFI mode, it tries to contact my PXE server and then goes straight to the Dell hardware diagnostics screen.

In the years past, I have only DHCP options 66 and 67 set for PXE booting.

Things Ive tried: Updating Optiplex BIOS to latest available on website Added IP helper on core router, pointed to my WDS server, for my client VLAN Removed 6667 options while using IP helper Added Option 60 set to PXEClient (my WDS and DHCP servers are seperate) Added in policies for UEFI boot hardware as seen HERE I dont have SCCM.

Im seeing some people user the boot path as smsbootx64wds.efi, but Im using just bootx64.not sure if thats related.

Just as a preface, I have servers and desktops on the same Subnet.

The thing that fixed it for me was that for some reason, my RemoteInstallBootx64 folder was missing a file (wdsmgfw.efi).

I found the file under C:WindowsSystem32RemInstbootx64 and just copy pasted it into RemoteInstallBootx64 and everything worked perfect after that.

I think there is a bug with this combo, where wdsmgfw.efi is left out when doing a new build from a 1803 image.

Copied the file from another place, and voil - UEFI PXE booting worked without a problem Take a look here also: 2 Share Report Save level 2 2y Hey, I know its a month later but thanks for posting that.

I had the same issue with the missing file and everything worked correctly after I copied that.

Share Report Save level 2 Op 2y so no dhcp options set, and no ip helpers, and on the same subnet I already have that file in that location:( 1 Share Report Save Continue this thread level 1 2y IT Manager Im assuming if youre using an IPHelper that your WDS server is in a different subnet to the PCs being built 1 Share Report Save level 2 Op 2y correct, WDS is 10.10.40.75 on VLAN 40, clients are 10.10.10.x on VLAN 10.

All VLANS have IP Helpers pointed to the DHCP servers 10.10.40.233 and 10.10.40.240.
