A:

In Recovery Console go to Utilities -> Disk Utility and select the outermost visible disk and erase.

    Please see Remove the Partition section in  Set up a Windows partition on your Mac - Apple Support .

    Thank you,

    But I didn't find anything that could help me in that support section.

    When I open up Boot Camp, I don't get the option to remove Windows - the box is greyed out.

    Only,

    "Create an installation disc"

    And,

    "Download latest software..."

    Are you trying to remove Windows more than once? Please post the output of the following Terminal command - diskutil list ?

    Well,

    I have tried to delete it through Disc Utilities and Boot Camp - yes, several times... :/

     

    From Terminal command I got:

     

      #:                       TYPE NAME                    SIZE       IDENTIFIER

       0:      GUID_partition_scheme                        *251.0 GB   disk0

    From your output, Windows has already been removed.

    4:                  Apple_HFS WIN7                    47.8 GB    disk0s4

     

    You do not have an MBR and your file system is Apple HFS not Windows NTFS. You may have reformatted the Windows partition after the BCA delete failed to clean up properly.

     

    If you want the disk space added back to your OS X side, the simplest and safest method is

     

    1. Back up OSX using Time Machine - Mac Basics: Time Machine backs up your Mac - Apple Support.

    2. Boot into Internet Recovery - OS X: About OS X Recovery - Apple Support.

    3. Erase your internal drive and restore from the TM backup in Step 1 - OS X Yosemite: Recover your entire system.

     

    Please be aware that TM does not backup Bootcamp partitions.

    Uff. Scary.

    But I will find some peace and time and fix it. And enlighten myself on those steps that you provided.

    I don't think I'm on Yosemite btw, I'm on: OS X 10.9.5.

    App Store prompts me to install Yosemite, but I heard it would slow my Mac down... :/

     

    Thank you Loner T.

    The procedure is not specific to Yosemite. It will work identically on Mavericks as well.

    Hey,

     

    Just tried it. Easy n smooth process. But.

    It didn't work.

     

    When internet recovering 'it' distinguished the two partitions - which to recover. And apparently left the other one(the WIN7) 'alone'.

    And when restoring from Time Machine it also asked what/where to restore - distinguishing the two separate partitions - and did not write over the WIN7 partition.

     

    :/

    In Step 3, you need to erase the entire disk, not just the OSX partition.

    M. Makes sense.

    I don't think I was given that option when in the process, at that point.

    But I will try again!

    Mr.T,

    You are awesome.

    I owe you a 'beer' next time you're in Stockholm.

     

    Tack så mycket Loner
