Well bugger me sideways with a rusty pitchfork! Out of total desperation I tried booting again from my normal drive and after about 20 mins it's booted from the "last working settings" thingy.
Not a clue what's happened like, but after a few google searches it seems I'm not the only one to have had a black screen of death! I'm totally baffled though as I haven't installed anything, or updated anything or added any new hardware. Fucking Windows.... lol
Still doesn't make me want to switch to Apple though
