I had a heck of a time getting windows 7 on a new core i3 because of the new usb. Finally found a program to re-image it with drivers even after I did the official MS way. If you have ps/2 ports then you should be able to get it on otherwise you'll need a way to get usb working.
For some time it has been suggested that one installs Windows first then linux.
That may change but I don't see it soon.
I prefer to have a single drive for each OS usually.
It is also possible that one could install Windows 10 and run a free virtual machine to run some other OS if they didn't want to dual boot. If you had an OEM builder version or full retail of windows 10 you could use it as the VM client.
https://build.opensuse.org/image_templates could run SELS maybe too.
