If you have Windows installed, You can directly boot (and install) from iso without burning it to DVD/CD/USB drive using EasyBCD.
In detail, if you want to install the ubuntu without flash drive and all other you have tried then you can also install it from network.

I have used Plop boot manager many times for installing different Linux Distros (including Ubuntu). It allows me to boot a machine for a device that is not supported by the bios. Very useful on machines that can not boot from USB.
