OS wont install?

[EastonUK1]

Hey,  i am new to all this so  dont know if this is the right place to ask this question but anyways.
I was looking on internet and found i could install Mac OS X on my windows, so i did everything and i partioned my C: drve, but i knew i did something wrong as it didnt let me set it to primary. I carried on as i thought nothing of it, i put the MAC OS X disc in my laptop and everything started fine and how it should, i went through all the installation then i had to select where i wanted OS X to install, i tried to find the partition i created but i couldnt find it so i though id select the drive with the most GB in, as soon is a selected this i know i have made a big mistake, Mac OS X has now deleted my windows 7 and replaced it with Mac OS X. Now i can not install Windows 7 back, i dont know how to remove Mac OS X, when i put my Windows OS disc in, it tells me to remove the disc and let windows start normally when i do this Mac OS X loads up. Is there anyway i can get windows back?!

Hi and welcome to the Gigabyte Forum.
Who's been a silly billy then? The only way for you to rid yourself of the OSX is to repartition the drive and then reformat it. I am not familiar with OSX(as I never enter the Dark Side) but I believe it uses a different formatting system.
