I currently have a full installation of Ubuntu 14.04 LTS on a 8GB USB drive (not a live USB, a full install). Which package do I install to mimic the "Install Ubuntu" application on the desktop of a live USB?

I realize it might be nearly 1GB in size, since it has to contain the whole installation media, but I'm perfectly fine with that.

Basically I'm looking for a way to plug my 8GB full installation USB drive into a new computer, double click the "Install Ubuntu" icon on the desktop, and then be able to follow the graphic installation wizard just like a regular Ubuntu install disc.

  • I doubt you can, it's not meant to install that way; you could try qemu + an .iso perhaps? Obviously you can't just transplant your installation as the hardware will differ - if it doesn't, you could use a compressed disk image & cat. – Mark Williams Mar 12 '15 at 10:02

As it turns out it's as easy as:

sudo apt-get install ubiquity ubiquity-frontend-gtk

Then ubiquity gtk_ui will bring up the exact same installer as the one from the Live USB.

Or alternatively you can copy the ubiquity.desktop file from the desktop of the Live USB if you want a nice GUI way of launching the installer.
