I have a 2012 MBP and a couple of weeks ago, I got the blinking ? folder on boot up. The HD wasn't recognized in Disk Utility so I assumed that the HD was dead. I bought a Crucial MX100 256GB SATA 2.5-Inch Internal Solid State Drive (CT256MX100SSD1) off of Amazon and installed it. I don't have a OS X Installation disk so I booted using Option Control R into internet recovery. Went to disk utility to erase the new SSD and then went to reinstall OS X Mountain Lion, selected the new SSD as the location and started the install. On the Install OS X Mountain Lion page it gives an estimated time remaining of 15 hours so I let it run all day yesterday only to have it get down to about 9 hours and then go to that blinking ? folder again. I tried the same process over night, still gave a 15 hour estimated time and, in the morning, I woke up to a blinking ? Folder. I know that it should not be taking this long to install the OS X and I've ruled out the internet connection being the issue. I have a bootable USB with Yosemite on it but the computer does not recognize that when you boot with the option key...it ends up pushing you back to internet recovery. I have absolutely no idea what to do next. Any ideas?
