If you do not want to play around with BCDedit or 3rd party tools like EasyBCD, it is quit easy to change boot order from within Windows 7.

I Know that this is kind of low tech, but I notice a lot of  questions out there regarding, how to change the boot order using BCDedit.

Here goes:

image Go to Computer – Properties.

Note: You can also do this by hitting the key combo Windows + Pause/Break or

image Click on Advanced System settings
image Open the Advanced tab

In the Startup and Recovery section click on Settings

Note: run sysdm.cpl to go directly to System Properties

image Now choose the OS you want to be the default one to load.
