How to set up a dual boot machine?

[RockGuitarDude]

If I install another OS along side windows on a different partition will it automatically adjust so that I get to choose which os to run at startup?

You might want to try the Operating Systems forum, as this is not a hardware question.

Short answer: sort of, depending on which OS it is. Generally you use the bootloader of whichever OS you installed first to choose which one will be loaded at startup.

From a hardware perspective - I would suggest a second HDD - then have separate OS's on separate drives and be able to switch between them. Mobile racks are the easy way to do this, and you will not be bothered by any inter-OS conflicts.
