OK. :-)

Right.

Oh. I expect it to already, in fact. That sounds like a grub or kernel
bug on your hardware, to be honest. Can you try adding "debug" to the
kernel command line before you boot? (hit 'e' to edit at the grub
menu).

Yes, I think so. I don't know how well the grub-probe code will cope
with Win EFI at the moment.

I'd hope so :-) One of the issues with EFI so far is that it's still a
bit fragile I think...
