This is all pretty counterintuitive, because the boot device list has "Removable media" as an entry, which is apparently useless - in fact, worse than useless, or I might have worked this out faster. Hopefully writing about it will save others from wasting time ..
In other news, since here am I writing.. I finished my degree in music & music technology recently (which is why i finally have time to fix my computer), it's been a fun ride and I achieved a bunch of things I always have wanted to do, like mixing for bad metal bands, writing and recording crazy dub tunes and playing sounds too quiet for anyone to hear in a gallery with some free wine. After a summer getting some programaction done (more on that later), mi novia y yo are going to South America for a while. We fly in to Buenos Aires in September and out of Lima in January (hopefully later) and so far that is the plan, I've never been out the UK for more than a few weeks before, i am really looking forward finally to some proper travelling in a very beautiful part of the world.
