2 OS's on my computer. how do i boot into eithe/or?

SO i have windows 7 on my main partition on my computer. and I'm starting a class that deals with some Windows Server 2003. So i tired installing Windows Server 2003 on my 10 gig partition. Now every time i boot my computer it goes to windows server 2003. Anyone know how i can boot back into 7? I guess i need a boot mangers, but i've never used/installed one before. Anyone have any knowledge on how to do this?

 

I can't say for sure but I believe this setup would have worked right if you had installed Windows Server 2003 first, in the same manner as creating a dual boot configuration with Windows XP or Vista and Windows 7. So, if you're willing to start this whole setup from scratch, that might a solution. However, someone else may have an easier, more direct solution.

 

Ya, agreed with the above, otherwise, here is a preliminary guide even though it is written for XP, it should work in 2K3. Probably easier is usaf's suggestion.

 

Eugh. thats not what i wanted to hear. Thanks for the input.
