Dell latitude E7480

[guerby]

Hi,

I'm trying netboot.xyz on a dell latitude E7480 laptop (UEFI network stack enabled, Secure boot disabled), I see the tftp happens but then just after a screen flicker the BIOS proposes F1 to retry boot, etc... On the exact same setup another (noname) laptop netboot.xyz works just fine
Is there any way to debug what's happening?

I am not familiar enough with netboot.xyz, but are you sure that it supports UEFI properly? If it doesn't, then maybe you need to boot the Dell laptop in legacy/CSM/BIOS mode to use netboot.xyz.

If you're getting an issue right after TFTP then I think you might be trying to boot a non-EFI version of ipxe in UEFI, which wouldn't work. How are you booting iPXE on your local network to get into netboot.xyz on these two machines? Is the no-name laptop also using UEFI mode or it is using legacy/CSM/BIOS mode?
