Good guess Nooby,
UFD = USB Flash Drives
UHD = USB Hard Drives
Basically you can also install LM15 on any (primary/logical) partition (SDcard/SSD/internal HD as long as support by LM15) the way I show you on video.
The LM15 installation process is real full system-install (NOT frugal/poorman installation/iso booting). It will work just like usual operating system, but it is portable and suppose to work on any PC whereas in window$ already done for a while.
Just rgd. Window$ portability you will find more flexibilities.
Some of ubuntu derivatives and work fine anywhere I go.
mozillux-13.5.1 works best for me. Faster booting speed and better hardware detection on many machine.
is there any other full installed linux distro bootable on any pc?
