Two ways: the easy way and the hard way.
If you have imaging software, you can make an identical copy of one hard
disk onto another hard disk. This is known as disk cloning. The second hard
disk will be an identical, bit-for-bit copy of the first hard disk. No need
to reinstall anything. Just boot from the second hard disk and everything is
there. And the cloning process takes only minutes to perform. Some hard disk
manufacturers may provide cloning software for their disks. Check the
manufacturer's web site.
If the manufacturer doesn't offer cloning software, Norton Ghost is a good
example of commercial disk cloning software, but there are others. Read

The hard way is to reinstall all your software on the new hard disk. There
is no way to simply 'move' applications from one disk to another that is
guaranteed to work.
