I got this awesome MacBook 2015 Retina couple of weeks ago, and it was a nightmare to install windows 8.1 using BootCamp, but then things worked fine for a few days. I noticed that intermittently, after I shutdown the Mac, using windows shutdown, at sometimes when I turn up the Mac, windows immediately crashes and is unable to load. After a few times of crashing, windows goes into repair mode which take a few minutes to finish. The biggest problem with this is, for some reason, windows deletes all of the executable files that were installed or downloaded. For example, any software, games, applications, etc.. are still in the program files folder, but their executables are deleted, which is major problem.. Any suggestions, answers to why windows would crash in the first place?
