Got stack in the installtion

[tahjhjhhhh]

Hello friends!

 

I hope you can help me in my dumb problem

 

 

I succeeded in loading the installation program of the retail version, but i can't continue installing because it says that I need to mark it as guid.

 

what I did so far is to install windows XP on 1 HDD and I divided it to two partitions - one for windows and the other for OS X (Leaved it unpartitioned) .

 

I started the installer and erase the partition I left for the OS X to "MAC OS X JOURNALED EXTENDED" ,

and when I tried to install I got the problem I mentioned above.

 

B.T.W windows won't start anymore, where I take it from here to fix things and make a dual boot of both opeartion systems?

 

 

 

Thanks a'head
