Ok, so here's my problem. I've got an .iso of Ubuntu Studio 13.04 that I'm trying to put on a USB stick and Ubuntu's startup disk creator keeps creating folders in the /tmp directory and then giving me errors complaing that it can't read from those directories. I don't know how to chmod the problem away given that these folders come up using randomly generated names during the installation process. But this is about all I know. What can I do from here? I did create a stick from the regular version of Ubuntu 13.04 that seemed to work just fine, but I want to move to 13.04 studio.
Edit: I should probably mention that I'm currently running 12.10 64-bit.
