Hi guys I have a 2014 macbook pro that i installed windows using bootcamp. During the process i deleted the 200mb partition used by mac os. Since then when i try to boot mac os, it shows a loading sign and after trying to load it I get an access denied sign and it stops there. Windows boots fine. I have installed a new instance of mavericks onto my external hard drive and i can boot properly. While there, my macbook pro ssd has 3 partitions. 1. Disk0s2 greyed out, 2. Machintosh hd, greyed out, 3. Boot camp, mounted and working fine. I went to win and formated that existing 200 mb partition to Fat, looked at my 180gb mac os partition and it had grey stripes in storage. I came back to external mac os install and tried to clone the efi partition of the existing install to my internal ssd, with carbon copy, it succseeded it says but it still doesn t boot, and that partition is always fat. I tried to mount the disk0s2 partition and it dorsn t do anything. I tried to format the 200mb partition but it says it doesn t support a journaled format. I have valuable data on my old mac install and i would like to retrieve it somehow. I tried everything under the sun on every forum and nothing works, i keep getting busy errors or permission error while trying to mount or convert/add gpt info to my ssd. Does anybody have any idea what can I do? Can t thank you enough!
