22.04 Custom iso

[Jerry Geis]

Hi,

Anyone successfully created a bootable ISO on 22.04 ?I have done one for
20.04 - with isolinux - but 22.04 no longer uses that.

This is the command I used - it completed successfully - but does not boot.

xorriso -as mkisofs -r -V 'Ubuntu 22.04.2 Custom' -no-emul-boot -o
/home/Jerry/CDROM.iso/Ubuntu.22.04/Ubuntu.22.04.2.Custom.2023.07.10.iso
