Acer Aspire R7- Installed, now booting to black screen with non-blinking cursor #iATKOS #ML2

Okay, so I need some help on this one. I finally got 10.8 installed on my R7, then as Clover rebooted then went into OSX on the HDD, it sat at a black screen with what looked like half a nonblinking cursor towards the upper left. I've tried a few boot flags, changing graphics settings, etc, but I honestly have NO idea what I can change to see if I can get this thing running from here. Does anyone have any ideas at all? It's such a tease to get it installed then have nothing...here's hoping.







Thanks!
