    Hi! I wanted to try game performance on Windows on my MacBook Pro so I installed Windows 10 to try it out. Since it wasn't much improvement I decided to remove the bootcamp partition.

    At first I did it manually but it didn't quite work well (Windows boot loader seemed to still be present and trying to look for the Windows partition). Then I reinstalled Windows via bootcamp in order to remove it from Bootcamp (the right way to do it). Now it doesn't seem to be any problem because it boots right into OS X but what happens is that there's a black screen right up when I press the power button. It's about 10 seconds of a black screen; no Apple logo. After those 10 seconds, the Apple logo appears and it seems to boot fine.

    What I think is that Windows UEFI boot loader is still present or something but it boots directly to OS X and that's why there's such delay. Any help with this?

    a) Repair permissions in disk utility;
    b) search for hard rive erros for disk utility;
    c) boot into recovery mode and do the same there, but search for extra partitions.
