OK, so I've had a lot of trouble running boot camp on my new iMac. The first time I tried to install it it ended up installing twice and the aero and flip 3D features weren't available. I used it for a while, but then I realized that something didn't seem to be right so I deleted the partition (it deleted my iChat buddy list somehow too and I had to delete my preferences to get it back). Whenever I restarted the computer it would still try to boot windows though for some reason and would say boot disc not available unless I held down the option key and selected OS X. Eventually I switched the start disc to OS X again. I tried installation again today and I got the same result. However, now it decreased my start up speed a lot. It took me two attempts to start up the computer after clicking restart in Vista, the first time I timed (it was taking so long I used the stopwatch on my phone) and I timed it at around 6 minutes not including the time before I started the stopwatch. I pressed the power button because it never loaded and tried again. Same thing for around 3 minutes. Now I deleted the Windows partition, but it takes about 38 seconds for OS X to boot, which I hear is much longer than normal. Sometimes it spends about 15 seconds on the blue screen, which I don't think is right. Is there something I can do?
