Extended partitions aren't generally regarded as bootable, as I assume
the difference is that they are missing parts that primary partitions
have, but I admit that I've never tried it.

Booting across devices seems to be a bit of a black art anyway,
especially where Windows or SCSI is involved. I can usually make it work
with LILO (I detest GRUB for some reason), but only after many horrible
hours of failure :-)

I'd probably regard MBR installation as a last resort for machines which
won't work otherwise, as it's annoying to have to reinstate it after
other OSen destroy the MBR as part of a normal installation.
