Only last week a friend gave me a perfectly good laptop that he was going to throw out because had removed the hard drive (faulty) from it so I installed LL3.4 on to a Sandisk micro USB 3 drive and it now runs exclusively from the USB drive and works like a dream.
These are the steps I took :-
(1) Downloaded LL3.4 ISO and burnt to DVD
(2) Reformatted & partitioned the USB Drive using synaptic as follows :- Partition One approx 28gb as Ext4 Parition Two approx 4gb as swapfile
(3) Run DVD and installed LL3.4 to USB and it automatically recognised both partitions and overwrote them but maintained the partition structure
(4) Rebooted from USB once installation completed and then run install updates followed by restricted extras and chromium
(5) Rebooted to double check that everything had been retained on reboot and happy to report that all is well with the world.
End result - Laptop destined for landfill, was repurposed using a 32gb USB Pendrive and an hours tinkering.
I hope this helps you in your quest
