I just installed v7 on this Gateway desktop. After I restarted, I came to the Darwin (Chameleon) boot loader and selected the partition v7 was installed on. However, I just get this gray screen with a silver apple that looks like it has a line going through it, nothing else. What might be my problem?

I tried the -x, -f, -v-f commands at the boot loader, but nothing happened. It just brought me back to the silver screen.

If you don't want people to guess what you're doing then post details/specs etc.

You're the only one sitting in front of your computer. People guess would be your OSX is not working.
