Can I dual boot 32bit and 64bit Windows 7, and if I can how?

Yes you can. Just make sure you have appropriate partitions for both operating systems installed. You can install either before or after, doesn't matter. Windows 7 64 bit setup cannot be started from within Windows 7 32 bit, so if you install that first, you will need to boot from your Windows 7 64 bit disk, click Custom Install during the install options and select the prepared hard disk or partition and Windows 7 will take care of the rest. Once installation is complete, you will have the option when your computer to select either version to boot into. Please note, you can only have 1 activated license, if you need to use both, you will need have both licensed separately, cannot use the same key. However, you can evaluate both for 30 days until decide which one is appropriate for your needs.
