==Overview== It is possible to install ubuntu from the internet by booting from a usb key or a mini-cd. This method of installation is called netinst in debian, so that name is used here.
==Getting the Image== The images for this are stored in /ubuntu/dists/gutsy/main/installer-i386/current/images/netboot/ (for gutsy 32bit). The cd image is mini.iso(9.1MB) and the image for usb keys is boot.img.gz(8.6MB)
==Preparing for Boot== The iso can be burnt to cd with any standard disc burning software, just be sure the iso is being used as a source image and not just a file on a data disk. br To prepare a usb key, back up any data that you have on it (any data will be overwritten) and zcat boot.img.gz >> /dev/sdX where X is the letter of your usb key
