I burn Ubuntu in a pen-drive. But each time I start with Ubuntu I need to change the configuration and select the option that I want to try Ubuntu not install removing my laptop operative system.
What can I do?
I found somewhere that an option is to install the system on the pendrive. But I found I need 8GB on the pen-drive, and following the manual I set just ~2500MB of persistent size for storing (step 4 in the window of the Universal USB Installer). How can I install it persistent on the pen-drive? Or I have already done so?
