Remove OSX but retain Windows?

[evilpaddy]

I am currently dual booting OSX and Windows 8.1 on two late 2013 iMacs.
I wish to remove the OSX partition to free up some space. Is there an easy way to do this without trashing the windows install?

It can be done.

If you don't use OSX, I believe you could clean install and get by with leaving 20-25gb for OSX.

How big is your HD? Does 20gb make that much of a difference?

Its a 500GB SSD.

I guess I could shrink the OSX partition to free up space for the windows drive and then setup Bootcamp to boot into Windows by default?

That way it would be easy to undo... 25GB for a redundant OSX partition is neither here nor there! Any special considerations before I mess about with the partition table?

You should be able to use disk part then partition manager to put all the space back to windows but something can always go wrong leaving you to reinstall windows from scratch.

My other reply is if you wanted to nuke windows completely.

The only way to resize an active W partition is to use camp tune (even then there are reports of it going bad).

It can be probably done if you use 3rd party boot loader such as refit
