Can't boot from the old drive
Hi guys, this is more a software than hardware question and I could really use your help! I have created a total mess upgrading my Mac with an SSD. I have already set up the new installation on the SSD, and wanted to transfer some of the files from the old drive to my NAS. Here's what happened: My Mac was runnon from the new SSD with OSX Yosemite and was put into sleep mode, NOT shutdown. I've replaced the hard drives and wanted to run the old system, but since it was in sleep it wanted to restore from Yosemite and messed up my boot on the old drive. Now there's no boot partition on my old drive, and my files (hundreds of pics and vids of my babies :/) aren't accessible. Please let me know if any of you have an idea on how to revert this mistake or if this description makes any sense at all :)
Thanks!
Is this a good question?
