I have a hard drive in an old computer which I would like to remove and
install into my new computer. I want to make this hard drive a secondary
hard drive in my new computer.

How do I go about doing removing and installing the hard drive or would it
be better for me to take the computer to a professional? Would my new
computer automatically recognize the hard drive or do I have to change some
settings somewhere in the BIOS?

I would also have to remove all the programs and operating system from the
old hard drive.
