This is my first Mac and I'm mainly A window user. I have a MacBook Pro (I think its a mid 2010 Model because it has i5 Processor), I also have a Mac OS X Snow Leopard Install DVD (Version 10.6.3) and a blank Western Digital harddrive. I wanted a clean install, on the orginal harddrive. The last screen i saw at the installation, was when It says there's only 45 min left for installation. Before it restarted and freeze at the gray apple screen, which I left it on for 1 hour. Then I forced restarted the mac off, with the Mac Install DVD in the DVD rom. Everytime I start the mac, I get the grey apple screen without the spinning pinwheel. I didn't know what to do. So I deceided to take the harddrive out and connect it to my window and manually deleted the Mac partation. Once I reconnected it back to the Mac, I had the same problem. Once I got the Install DVD out, I started getting a flashing folder with a question mark. I've realised that this might be because I've deleted the partation. I tried to figer out how to get it formated but so far now I'm only getting format guides for a mac. When I open the Startup manger (the ALT Key at thet start up) I don't see any harddrives and if I inset the Mac Install DVD, that's all I can see. I can detect the harddrive on my window machine. I just want a clean install, I don't mind if I can install it on the old or the new harddrive. It would be much appreciated if someone can help me.
