Thanks for the detailed tutorial! I've tried this tutorial and a number of other ones for installing Ubuntu onto both SD card and USB flash drive and I always follow the instructions to a "t" (or at least I think I do), but in every case, after the step to copy the installation image to the SD card or USB flash drive, something goes wrong and both Linux and Windows "think" that the media is blank/unformatted. Do you have any ideas/suggestions about what I'm doing wrong? Also, if you have any pointers to a good (and simple) tutorial on the Linux/Unix mount command, I'd be grateful!

Thanks!
