So I've configured the UEFI to boot PXE, and I can see that it boots "succesfully":

Booting from PXE Device 1: Integrated NIC 1Port 1 Partition 1

Start PXE over IPV4.

Station IP address is blaah

Server IP address is foobar

NBP filename is bootx64.efi

NBP filesize is 1341560 Bytes

Downloading NBP file...

NBP file downloaded succesfully.

Fetching Netboot Image

 

And at this point the screen clears and the server says next:

Booting local disk...

error: no such device /efi/boot/bootx64.efi

 

Why does it jump to booting from local disk and not continue with PXE?

 

That server HAS booted from PXE before, but we changed the role of it and manually installed ESXi on the BOSS drives. (240GB SSD). Which BTW caused me hours to figure out. We have 2 RAID controllers...the BOSS thing and the other internal one H750 if I recall. I disabled the H750 from the boot sequence and ONLY, I stress ONLY(!!!), had PXE boot in there, and still it kept finding ESXi somehow. It looks to me like I can select PXE and H750 to be in the boot sequence, and if those fail somehow, it will automatically jump to the BOSS boot. The only way to prevent ESXi booting, was to wipe the BOSS drives clean. Well....now it complains it can't find the boot files, but still doesn't boot PXE.

What should I do?
