Late 2012 iMac 3TB does not support Boot Camp Assistant
Got my new customized iMac 27' yeasterday. After installing some soft, I decided to install Windows 7 as second OS on Boot Camp. After clicking the Boot Camp Assistant icon, programm opens, and immediately it shows error "Boot Camp Assistaint does not support Windows installation on this iMac 3TB" or something like that (I have a russian version of dashboard/OS). Only option available at that moment - button "OK", which exits Boot Camp A|ssistant.
So... Any suggestions on how to solve the problem? I really need Windows as second OS, and don't want to install it like a virtual/emulator machine.
My customized iMac "loadout" is Core i7 3.4, 16Gb DDR, Nvidia GeForce 680MX 2Gb, 3TB Hard Drive.
P.S. I thought this may be solved by separating Hard Drive into partitions (main, which is for Mac OS, and little tome for Windows, formated into MS DOS FAT system), still - this has not helped me.
iMac, OS X Mountain Lion (10.8.2)
