Cannot get autoinstall 22.04 to boot

Hello I am trying to make an ubuntu 22.04 autoinstall usb

20.04 boots fine but I cannot get 22.04 going.

I am running this on a headless & keyboardless server as my cat chewed through my keyboard cable

In the grub I have changed the line to many things now

linux   /casper/vmlinuz   quiet   autoinstall   ds=nocloud\;s=/cdrom/nocloud/  ---linux   /casper/vmlinuz   quiet   autoinstall   ---linux   /casper/vmlinuz   quiet   autoinstall   ds=nocloud;s=/cdrom/nocloud/  ---linux   /casper/vmlinuz   autoinstall   quiet   ---

My user-data file is

#cloud-configautoinstall:  version: 1  identity:    hostname: ubuntusrv    password: "REDACTED"    username: REDACTED  ssh:    install-server: yes    authorized-keys:      - "ssh-rsa REDACTED"    allow-pw: no

Am I doing anything wrong?

The iso command is

xorriso -as mkisofs -r -V "ubuntu-22-04-autoinstall" -J-boot-load-size 4 -boot-info-table -input-charset utf-8 -eltorito-alt-boot -b bootpart/eltorito_img1_bios.img -no-emul-boot -o ../installer22.04.iso .

Thanks in advance here's hoping. I've been trying this for days
