I installed Windows Vista Ultimate 32bit the other day on my MacPro. I use a 1TB drive as my primary drive and Mac OSX boot drive. This 1TB drive is in bay 1. I also have a 500GB drive in bay 2 that I installed Windows Vista on. When I hold down the option key when I boot my Mac to choose to boot up Windows instead of Mac OSX, I see three drives that I can boot. Mac OSX, and two Windows drives. Booting the middle Windows drive just brings up a black screen that says "GRUB" on the top left with a blinking underscore. Booting the last Windows drive boots up Vista. Is there anyway to remove that middle Windows drive from my BootCamp screen? This wouldn't be an issue if my Mac didn't default to booting that middle drive when I want Windows, but since it does I'd like to remove that middle drive if possible.
