PXE booting Kubuntu

[Mimir]

Hi,

I'm trying to boot the Kubuntu ISO using PXE. At this moment I'm trying to get it done using BIOS, but I also need to get it working under UEFI sadly.

I hope someone can help me because I'm a bit confused on how this is supposed to work. I've been searching on Google and DDG for far too long, so I hope someone here is able to assist me. It always takes forever to load with lot's of network activity on the port. It seems to want to load the ISO file.

Here is what I tried:

Method 1:

LABEL Kubuntu 19.04
menu label Kubuntu 19.04
TEXT HELP
This should boot Kubuntu
ENDTEXT
APPEND iso raw initrd=/kubuntu-19.04-desktop-amd64.iso

Result:

Boot failed: press a key to retry, or wait for reset...

Method 2:

LABEL Kubuntu 19.04
menu label Kubuntu 19.04
TEXT HELP
This should boot Kubuntu
ENDTEXT
LINUX /syslinux603/memdisk
APPEND iso raw initrd=/kubuntu-19.04-desktop-amd64.iso

Result:

Boot failed: press a key to retry, or wait for reset...

This actually boots the ISO file, but I get stuck. I get on the black Kubuntu screen with the blue logo, after that (takes a while) I get an error.

LABEL Kubuntu 19.04
menu label Kubuntu 19.04
TEXT HELP
This should boot Kubuntu
ENDTEXT
KERNEL memdisk
APPEND iso
INITRD /kubuntu-19.04-desktop-amd64.iso

Error message:
