You should have cloned your drive . Plug the new drive , format it and use Carbon Copy Cloner or SuperDuper ! I use this one . After cloning , reinstall the bootloader on the cloned drive and you ' re good to go . The OS won ' t even tell that it ' s installed on another drive . Cheers ! <| sep |> For me , it was a combination of choosing instant gratification over long term goals , sheltering myself from sexual harassmentshallow relationships , and believing all the stories about weight loss being impossible . So it was very easy to give up the moment it got difficult . I ' m an intelligent person and successful at every other goal I ' ve set for myself , so I felt like a total failure for not being able to lose weight even though , to be honest , I ' d never really tried until this time around .
