Hi, I'm trying to install Windows 8.1 via Bootcamp on my newly Mavericks-upgraded late 2012 iMac. I get to Windows 8.1 installation setup, and after choosing the right partition I get "Can't install to partition etc...". Anyone knows how to fix this? I made a bootable USB (Corsair 32gb USB3 stick) with Bootcamp, but doesn't work. I also used "Format" for the Bootcamp partition in the Windows 8.1 setup. Any advice would be great, otherwise I'm enjoying Mavericks. OSX has become a very mature and stable OS, and most of the bad ideas from Lion have been removed. Thanks!
