I know how to create a bootable USB (pendrive), or CD, to install Ubuntu on to a hard disk. But I already had an installed system on USB, and don't have any additional USB anymore. So I booted into the system on USB already, how can I install a new Ubuntu system (or copy of my USB system) into the target hard disk?

There is a method of installing anew from an ISO file without burning it to a disc:

  1. Download an installer ISO. If you'll have a good Internet connection while installing, mini.iso is an excellent option, giving a very small ISO file that can install any Ubuntu flavor.
  2. Open a terminal by pressing Ctrl+Alt+T.

  3. Install grml-rescueboot:

    sudo apt install grml-rescueboot

  4. Move the installer ISO you downloaded to /boot/grml (replace filename.iso with the actual ISO filename):

    sudo mv ~/Downloads/filename.iso /boot/grml/

  5. Update GRUB:

    sudo update-grub

  6. Reboot and select the ISO.

  7. Install the desired flavor of Ubuntu, making sure to install it on the hard drive and not the USB drive.
