I am trying to install ubuntu-22.04-2-desktop-amd64.iso on an HP Z210 computer. When I go into the BIOS boot menu with a bootable USB inserted, the BIOS does not recognize the USB stick. So I need to burn the iso to a DVD but at 4.9 GB it is too big to fit. I don't have any dual-sided DVD drives. I mounted and browsed the iso but don't see anything that I could delete like foreign language support.

Does anybody have a method to reduce the size of the ISO to fit on a 4.7 GB DVD disk?

Not really. You could download the ISO, mount it using squash-fs and then remove packages, recreate the ISO. It is a lot of work and there are better options. 2 of them:

  1. use the server ISO and use sudo apt install ubuntu-desktop to install Ubuntu. There are more DE's you can install if you do not want gnome3.

  2. download the ISO and boot from it from GRUB. You can add the ISO to the GRUB boot options and pick it from there. Here is an example

Slightly altered to remove the version:

menuentry 'UbuntuCustom3' {
  set root='hd0,5'
  set isofile=/ubuntu.iso
  loopback loop $isofile
  linux (loop)/install/vmlinuz boot=install iso-scan/filename="${isofile}" noprompt noeject
  initrd (loop)/install/initrd.gz
}

You could try the Ubuntu Minimal ISO. They have one for each release, 24.04 is located here.

https://cloud-images.ubuntu.com/minimal/releases/noble/release/

The one for 24.04 is about 250 MB I think. Should fit easily on a CD let alone a DVD. I havent tried it myself but in the past Ubuntu would have both a DVD ISO and a CD ISO. I installed using the CD ISO, then enabled the universe repository, and it downloaded anything that wasnt on the CD from the internet. Worked pretty well but that was a couple releases ago.

There is no way to compress the Ubuntu ISO image, because it is already compressed unto its extremity.

You could install some other Ubuntu Flavor, which has a desktop that is less in size then Ubuntu's (Lubuntu, Kubuntu, Xubuntu).
