I have bought MacBook Pro with OS X Yosemite two days ago. After I transferred my files through Windows sharing I come to know that Disk utility didn't install properly as it says damaged or incomplete. So I had to restore is as new.
First time it took more than 8 hrs because I slept after 5 hrs of wait. Then again I had to repair because I didn't find iMovie, iPhoto etc because it was in purchased items in iTunes but it also take ages and also I stopped migration through apple app because of same problem, took ages.
So I was afraid if data was saved somewhere so I restored again. I started at 3pm and it's 6.46 and it's not even half of it and saying 33 hours left. I followed Youtube videos, they says their repair takes just half an hour! Need help in a detailed and easy way. What does it mean by boot?
