So, I got the question mark in the folder and then used the internet repair thing on my Macbook Pro 13 2012. I erased a 16gb SD card in the utility disk section and made it my partition thingy (really wasn't clear on what I was doing). Then I installed Lion OS x onto it. So, then I created a new account and all that with my new reinstalled OS...and it didn't work. It stalled like crazy after I removed the SD card and I had to hold down the power button to shut down the laptop. And then when I rebooted it the question mark in the folder came up AGAIN. I have no idea what I'm doing. I'm willing to pay the 169 with apple that it costs to replace the hard drive if it means they can get my old data for me. But...can they? Is it too late?
