I was on this forum a few years ago to get my dell mini 10v hacked into a Mac. Everything worked perfectly fine and now, someone updated my iTunes without my knowledge and it screwed everything up. When I start up, I get the Mac image with the X on it.

ANY, and I mean ANY advice would be greatly appreciated. I searched a bit on here and didn't find anything.

If there's a thread about this already (I wouldn't be surprised if there is) a link would be appreciated as well.

I guess my question is, is there anyway to go back through start-up?
I don't have a seperate laptop or desktop,so I feel that I may be screwed.

Thanks in advance!
