And here's the output from the hcl script:
====

The OS installed happily after disabling secure boot and enabling legacy boot.
I'm still trying to get the wireless working, but I think I may have found the solution to that so I won't bother with detailing that until I've exhausted my options.
I also get a consistent error message which I'm not sure I should be concerned about or not:
====
nouveau ! [device] unknown Fermi chipset
nouveau E [device] unknown chipset, 0x0d7000a2
nouveau E [DRM] failed to create 0x80000080, -22

Can anyone tell me what that means? I can see it's from the nvidia drivers, but beyond that, is this a problem that I should be worrying about or is it largely irrelevant?
Thanks,
