I'm trying to install windows 7 on my mac using bootcamp. I got the drivers and successfully partitioned 80 GB of space(I have a 250GB hard drive) for the Windows partition. However, after restarting it in order to install the OS, it shows a black screen with a white line blinking and it simply was like that for a half-hour. I then stopped the installation, booted back into Mac OS X, and then deleted the partition for Windows. I'm running BootCamp 4.0.1. First off, should you install the drivers before installing the OS? Second off, should you only install the 64-bit version, not the 32-bit?
