Two methods for creating Full install pendrives: How to make a live Ubuntu 18. Note that once booted, both methods run at about the same speed. Once casper-rw is full, the drive will not boot.ĩ) You can run VBox and use virtual machines.

You can then install as you would to HDD, either automated install or using 'something else'.ġ) You can use the persistent pendrive to install Ubuntu to another computer.Ģ) A persistent install takes up less space on the pendrive.ģ) You can reset the pendrive by overwriting the old casper-rw file with a new one.Ĥ) The install to pendrive takes less time.ġ) You can update files and upgrade Ubuntu versions.Ģ) If you have problems or wish to modify, the solution is the same as with an internal install, (You can ask for help in these forums).Ĥ) Better security, you can use full encryption.ħ) A persistent install is often limited to a 4GB casper-rw and a 4GB home-rw persistence file, to get more persistence requires persistence partitions. It is safest to first unplug your internal drive and then insert your USB. If you want to run Ubuntu from USB just like from an internal drive you can make a Full install to USB.
