I've only had my Mac about two weeks and boot camp for about a week. The alt/option at boot has never seemed to work for me, maybe I don't know when to do it or how long to press it. I've been using "Startup Disk" and more recently "Boot Champ". Right now, when I try to startup in Windows a blank black screen comes up and nothing ever happens, I end up having to power down and back up.
I just installed Parallels the other day and when I ran it for the first time I had three options:
New Windows Installation
Migrate Windows from PC
Use your Virtual Machines
Since I already had Windows 7 installed via Boot Camp, I assumed I should use "Use your Virtual Machines". Was that the right choice, or should it have been another one?
