Hi is it possible to run a dual boot with opensuse leap 42.1 and windows 10 pro on 2 or more different hard drives?
What I want to do is have a solid state drive with my linux o/s on it and have my home partition on a separate hard drive and my windows o/s on a third hard drive with 2 partitions on the third drive.
If this this is possible what do I install first? Which drive is the boot drive in my efi? Can I have gpt drives?
Any help would be appreciated.

Yes, it's easy. Or would be if M$oft was a bunch of ass-holes.

I think you'll find Win 10 requires both UEFI and gpt. As do most Linux installers once they detect UEFI firmware, so go with all gpt just for your own sanity.
And install Win10 first - you'll regret it if you don't. You may regret it anyway - it may force itself on the SSD. If it does it should onlly be a small partition. Take note of the EFI partition it creates.
Then install Linux - it should detect (and use) the EFI partition Win10 creates, but if not make sure you point the installer at it; usually in the partitioning section of "something else" or "advanced partitioning".

Like I said, easy.

You can do this but not all uefi bios's seem to act like you'd think.

If you don't want to mess with it too much you may be able to run a free virtual machine instead.

Only problem is virtual machines are very limiting. Lots of software (especially games or 3d video apps) won't work in a virtual machine.

"you may be able "

Without knowing what you have and what you want to run I still can't say if you could run a vm or not. Some folks on this site claim good results in a vm.



In general linux and modern systems can still work with windows either with our without changing bios/uefi settings. A few distro's work well in both uefi and secure boot on some systems. Many more work in uefi and disable secure boot. You should be able to use some legacy bios setting and legacy boot to use what ever you want.

I'd load or save my windows 10 disk. Then remove it from the system. Then install your linux disk and load to it. Then replace windows 10. If your linux supported uefi and secure boot you will be able to switch in F key. Otherwise you will have to edit bios settings for each boot. Not a bit deal but a bother.
