Hi - about a month ago in my Macbook Pro 2010 I had my main HD changed to a SSD and my optical drive removed for the original HD. All was well. This morning I opened the lid and the desktop was locked up. Did a hard reboot, and now I can't get past the grey screen. I've tried everything I can think of: Reset PRAM - (this actually got me a little further as originally I couldn't even get to the startup chime) Hook Up External Monitor - never fires on Hooked Up USB Hard Drive (which I used to be able to boot off) - not detected Hooked up Optical Drive via USB w/ installation disks - not detected. Holding down "option" when booting doesn't give me any menu. What do you think the problem is? I have Apple Care, but I'm not sure if they would service it since it's been modified? Thanks in advance.
