Good morning everyone. PLEASE HELP!!!
Yesterday I wanted to add a Windows 8.1 to my Macbook pro via Boot Camp and suddenly formatted (fully, even backups) all partitions... Now I have only Win 8.1 but there are several issues with the drivers, so I want to at least restore OS X... Any suggestions???
P.S. I have tried to downoad OS by Command+Option+R at start up and but it needs OS Lion which is not listed in the Appstore right now...
MacBook Pro, OS X Yosemite (10.10.2)
Hi gorlazyan,
Welcome to the Apple Support Communities!
I understand that it seems like the Mac OS X partition was erased from your computer and you would like to reinstall it. In this situation I would recommend booting into OS X Recovery using Command + R, not Command + Option + R. When you boot into the Recovery System using this method, it will install the most recent version of OS X previously installed on your computer. Please refer to the attached article for further information.
OS X: About OS X Recovery - Apple Support
Best regards,
Joe
The problem is that when I boot my computer and want to internet recovery it suggests to download and install OS X Lion, but when I try to download it, I get a message that "Mac OS X Lion is temporary unavailable in App Store. Please try again later".
Then I just install OS X Yosemite from other computer to my USB flash and everything went well!!!
Here is the guide (please pay attention, there are some mistakes, read the full guide in COMMENTS)
