I want that on my notebook the operating systems Windows 10 Pro and Windows 8.1 are installed at the same time and I have not tried it and know me with such a thing not very well and ask people who are more familiar with software, it is feasible and what operating system should you install first and then try it with the next operating system?
You could load a virtual machine on your PC, so you can have different operating systems on a PC. For example, the VMware

That's fine. But why do you need that?
But why do you need that? Because some of the tools and programs I need working on Windows 10 can't be installed on Windows 8.1 and vice versa.
Okay, but it's pretty funny. Actually, most of it runs on Win8.1 and Win10. Win7 would be there again a bigger difference.

You can install several operating systems on a PC.
At the time, this was really done at the hardware level, with partitions and the boot menu. This method is however outdated and cumbersome.
Today you use virtual machines. A virtual machine is nothing more than an emulator running a second operating system. The second operating system does not notice that it actually runs on a virtual hardware. Today's virtual machines can use the graphics card easily. The program https://my.vmware.com/de/web/vmware/free#desktop_end_user_computing/vmware_workstation_player/15_0 is probably the best-known virtual machine and free.
Has other reasons, synonymous older USB sticks running on Windows 7, but can't be seen on Windows 10 and I will use them in the future even on Windows 8.1 and not throw away.
