Multi Boot for DAW’s

Firstly, I don’t know very much about this topic so i’m looking for some advice that I can understand, let’s go for absolute beginner!

I’ve been reading up on this after some advice to look into it for when I purchase a new PC for music production.

From what i’ve read, I believe it means the following:

In order to maintain an efficent running operating system to use a DAW on you can install 2 or more versions of an operating system onto your PC by partioning your hard drive into seperate smaller hard drives and using each of these for a specific function,

i.e.

Hard Drive 1 for General use, which would include: internet, office, games etc

Hard Drive 2 for the DAW

In addition to this you could include another partion for storing audio files onto.

Is this correct?

Once I have an answer i’ll post some more questions about it.
