Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
- Install the Apple Boot Camp software. Purchase Windows XP w/Service Pak2, Vista, or Windows 7. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
- Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
- VM Fusionand Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
- CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
- VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

does this make my macbook pro slower???
And P.S. Please always remember to do a simple Google search before posting. A search for "how to run Windows on Mac" would have yielded the answer to your question.

Generally it won't slow things down *unless* you get cramped on RAM and OSX starts paging to disk. The one thing a virtual machine running Windows is going to consume is RAM, since you'll need to support the OS and any running programs. The slowness arises not so much from Windows bogging down the processor (I have Windows 7 running Excel 2010, OSX Acrobat Professional, Mail, Safari and a number of other programs running right now and my CPU usage is down at 10%) but more from reading and writing to disk which happens if the system runs out of RAM.
Remember that OSX now wants 2GB of RAM as a minimum, and Windows 7 has only slightly lighter specifications. Modern operating systems do have higher RAM requirements than older ones did.
I've got this running on a MacBook Air (which means 4GB RAM maximum) with 1GB devoted to Windows 7 and I'm not running into issues. Of course, that Windows machine won't (easily) support running a bunch of programs at the same time without Windows being forced to page itself, but then I don't normally run more than one or two Windows programs at a time. On my MacBook Pro with 8GB of RAM I've upped the Windows Virtual Machine RAM to 2GB and, again, I don't notice a problem.
Now if you have a "RAM cramped" machine (say a 2GB machine) you could run into issues much more quickly. In such a situation, Windows XP (assuming you can get a licensed version to install), even with its issues on security and the like, might be what you'd want for the Windows OS since it has a smaller footprint than Windows 7.
