I just built my first Linux machine (Fedora distribution) and love it. For my professional work, having access to Windows would help tremendously, and I'd like to be install Windows and have a choice of OS upon boot: Fedora or Windows. I've also read a lot on how to do this and a common warning I see is, "Be careful, Windows will overwite the Master Boot Record with its own instruction set." My (seemingly) simple question is - can I physically install another hard drive, install Windows on that disk, and, if I want to use Windows, change the boot order in BIOS to make this disk the first?
To be specific to your question: Yes you can.
