Well, I don't understand UEFI and all that stuff, but ...

When I tried to install SUSE on this laptop, it quite happily installed - UEFI - pointing to the UEFI partition it created on sdb. Of course, the laptop boots Windows off sda, so SUSE-install (presumably grub) put it in the wrong place and the laptop doesn't even realise SUSE is there :-(

Cheers,
Wol

I did that at first, the first time I installed to a UEFI laptop. And ended up using the UEFI boot menu to switch.

I later realised that all OSs should _add_ to the same UEFI partition, that should already be there if you got an off the shelf laptop with WhineDoze preinstalled.

So I now first increase the size of the UEFI partition, and then install Fedora on another disk with /boot/efi pointing to the same UEFI partition. And since then, dual boot works fine and can be driven from the grub menu.
