I have an Intel PC. I have installed iDeneb Mac OS X in my PC. It's running fine.

After that I thought about installing Snow Leopard for running the iPad SDK. So I bought a retail Snow Leopard and booted it with Rebel EFI boot loader. When I was installing Snow Leopard, at the end of installation, setup gives an error. So I restarted my PC and boot with Rebel and I saw that the Mac was there so I booted that into safe mode and Mac OS X runs. After that I installed iPad SDK. But when I try to create an application, Xcode is not responsive. It hangs when I choose new project, give it a name and save it on disk. After just as I gave name and choose save it hangs.

Is there any way I can repair my Mac OS X without reinstalling? I have also been unable to boot into normal mode and also without Rebel CD. So I want to boot without Rebel CD and also want to run iPad SDK.
