Hi Guys
I need help

I own a macbook pro mid 2012. The hdd is replaced with a 256 GB ssd (sierra installed). I tried to install Windows10 so I launch bootcamp and prepared a usb with the Windows ISO, than I created a 50 GB bootcamp partition for Windows10. The machine restarted and I started following the steps. After accepting the terms I choosed advanced to perform a new install. At that moment Windows told that the MBR partition is not supported. I launched DOS and cleaned than converted the partition from MBR to GPT as advised on a YouTube video. After rebooting I noticed the the efi and the ssd HD are lost and couldn't boot on macos Sierra. I'm afraid to lost all my data I didn't made a backup. Is there a solution to recover the partition ?


Thanks for your support
