Is there a way to delete Mac partition after boot camp?

    I have boot camp on a 2011 MBP and I want to fully wipe the OSX partition to only have windows. I don't want to reinstall Windows.

    Is there a way to do this?

    I've tried formatting the Mac partition from windows but I get an error.

    I tried using cmd line formatting in safe-mode and that didn't help either. Incorrect parameter error.

    I thought about partitioning the Mac portion (keeping OS X) again but I read that I can't have 3 partitions.

    Is this possible?

    Doing so would prevent you from ever getting any firmware updates for your hardware. You can shrink the OS X partition, but I'd still keep it around for those purposes.

    Why would anyone want to overpay to run Windows exclusively on a Mac is beyond me.

    This. I mean, Apple hardware is still superior to pretty much everything else out there, but it just isn't meant to be primarily run by anything other than OS X. Just because Windows 10 functions like it should on your MBP, doesn't mean you should kill OS X because of it. :p

    I get frustrated when I see people do this in starbucks.

    You might be able to but you would be better off making the MAC OS volume as small as you can then leave the rest for windows. If that's what you really want to do lol

    Yeah, this should be possible. But, OSX will be re-written as a separate partition formatted as NTFS. You can probably do this from inside Windows and format the drive from there. Alternatively, boot from recovery and clear the partition.

    With GPT disks you can have more than three primary partitions with MBR that was the limit.

    Keep OSX in the smallest partition it'll fit in ~12 to 14GB and let it go.

    The easiest way to do it, is to set the largest partition you can for Windows running the bootcamp assistant. Just remove everything you don't need in OS X, and then create a large windows partition

    Why do I see so often a Thread Starter not returning. I see this as trolling. Let it go!
