<< Solved >> el capitan and high sierra on two separate SSD´s

[progma]

Hi!
I can't really find the answer somewhere.
I have an working 10.11.5 build on a samsung evo 850 ssd today. I just bought an samsung 970 NVMe M.2 and want to install High sierra on that one and keep el capitan on the old one, so I can use it for backup if something happens with high sierra. Before i do that. Is it possible to have two fully functional OSX with same bios settings?
