It turned out that the bios has a "Windows 8" setting that actually should
be called something like "Any EFI OS". Once I'd enabled the Windows 8
settings and re-installed, putting grub in the Windows disk's EFI
partition, then all went well.

It seems that Gigabyte only think in terms of Windows (I made the mistake
of referring to Ubuntu in my support request to them and got the usual "We
do not support linux" response), though the fact that Windows 7 can be
installed in EFI mode seems to have escaped them.
