I have a laptop with NO HARD DRIVE. (It's dead and gone.) I want to boot and run Ubuntu from a USB flash drive. (Not just a 'test drive'.)
First question: Is there a difference between a LiveUSB 'Install' stick and a LiveUSB 'Run' stick? I have used the 'Universal USB Installer' from pendrivelinux.com to make a 'LiveUSB' stick with Ubuntu 11.10. It seems to run fine the first time I use it, but on subsequent boots, it has a variety of problems. Is this stick what I want for the scenario I described, or should I somehow install Linux to a bootable USB flash drive? (How?)
Edit: Additional info: Thanks, all, for your feedback. The installer won't install to my 4GB stick because it required 4.3 GB. That's as far as I got. I hope to continue this exercise at some later date.
