Need help on Dual Boot
 

Hi there,
This is my first Post after several hours of reading this board...

I am a complete Noob, und I am very new at MAC OS. I read so much about Mac, so I want to try it.
I Installed Ideneb on my PC, and it looks fine. So I start to read much more and I found out, that a Retail DVD can be used.
I close my Eyes and installed 10.5.6 on my laptop. After some weeks of reading, some trys, some Errors this laptop is running fine now.

Of Course this laptop, a Samsung Madril R560, has only one HD. And there are three OS installed: On the first 2 Partitions there is WinVista and WIn7. Both installed first and running fine. Then I installed MacOS X on 3th Partition. This is also workin very fine. Max OS has to boot from a Boot123 CD, Vista/Win7 is booting from HD.( HD is GUID formated)

Here is my question: How can I boot all from HD without reinstalling? I do same trys, but it fails. Is there anyone who can help a complete Noob?

Sorry for my bad English :)

thank you
