@george1421 With few modifications of your description, I’m getting one step closer. However I’m stuck after “Trying to download and mount… .iso” , i get “wget: short write: no space left on device”…
Any ideas how to move forward from here?

regards,

@george1421 Guides there seem to be outdated… at least for ubuntu. It looks like after Ubuntu 18, the concept for netboot changed a lot and it is more like booting live cd using something called “casper”…
I did played a bit with it, but couldn’t make it work.
Any fresh ideas are much appreciated… Also I’m more interested in UEFI boot.

Regards,

@george1421 Thank you for your time to write.
I see these guides are mainly for Legacy (BIOS) boot. Do you think I can somehow convert them to work for UEFI?

I can’t seem to find proper documentation about how to add menu entries for booting ISO files like Live CD or any ISO Install Media.
Is it possible to do via the FOG Web interface or I need to do some work on the console directly?
Please help!

@george1421 Thank you for your time to write.
I’ve added these options as well, however nothing changed, I still get the same error.
Check the OFFER packet to see if that’s the desired option or I’m missing something:

@george1421 DHCP server is isc dhcp server running on separate (from fog) ubuntu server.
Here is the requested information, it looks correct, or at least much like the legacy OFFER with only difference in the boot file:

I’m facing trouble booting UEFI machines.

It seems UEFI not even trying to download the boot file from TFTP.

Any help will be much appreciated.
