Thanks for clarifying on iPXE and FOS Linux.

Why refind is working is it is configured to find “windows” and boot it out of the box.

I tried configuring refind to boot grub and it partially works.
Grub shows and I can boot windows from it, but when booting Ubuntu Server I get error: failed to install protocols even though I manually installed grub with --disable-shim-lock and disabled secure boot.
Looks like it’s not secure boot related, but more like driver issue and I probably should try that iPXE chain load thing.

What you need is for iPXE to chain load grub.efi from the first partition so that the grub menu starts up correctly so you can dual boot.
I guess that I need to modify default.ipxe?
Could you direct me?

Hi,
I have couple of Dell PowerEdge T150 that are used as FOG clients. They have dualboot (WS2022 and Ubuntu Server).
WOL, imaging and restoring works perfectly, but I can’t get booting from PXE menu working.

I tried different exit options and I managed to get Windows Boot Manager working with rEFInd, BUT I need to boot to grub because of dual boot. Booting without FOG works as expected (into GRUB).

Could it be issue that disk is seen as RAID Controller in UEFI and FOG expects eg. SATA device?

Thanks,
