Is it possible to have multiple windows on one PC?

Question

System administration

Greetings, this question arose, now I have windows 10, it became necessary to install windows 7 as a second system (virtualization is not suitable) and so, if I pump windows 7 to another disk partition, will I not lose access to the main windows 10 and will there be a choice of OS when starting the pc?
