I want to deploy ubuntu to multiple computers with custom preinstalled apps and packages. I have customised an OEM installation (on a VM) but how do I capture it to a bootable image/installer.

Like in windows, after sysprep, you can capture the install.wim file with windows pe live boot and then make a custom iso.

    See if this works for you. It uses an .IMG file not an .ISO file. https://askubuntu.com/q/1300540/43926 – C.S.Cameron Jul 04 '23 at 11:59
  • You should be able to create an image of the installed system and then clone it to another computer using Clonezilla: https://clonezilla.org/ . However, this is not "customized installation", this is just cloning of the installed system from one computer to another. – raj Jul 04 '23 at 12:12

  1. without any especial tools you can make filesystem.squashfs from Ubuntu root partition as a backup so you can restore your Ubuntu and you can make Ubuntu live USB by this file to install your ubuntu on another pc.
  2. with cubic you can customize your Ubuntu iso and get your iso file which can used to make live USB
