i had same situation like you. Windows 8.1 Pro in partition 1 and I dont want to format it whatsover. so here are what I did:
the raw image i've got from here wont boot ever (the clover one), i can boot to the chameleon, but it never got to installer no matter what i did. but then i read about clover bootdisk utility by cvad, so i use two usb boot via usb created by bootdisk utility (it booted fine from clover, no go with chameleon), then plug the usb with installer, boot the osx installer. then finish your installation, after that remove (when the restart-countdown shows up), unplug the usb installer.
still booting from your bootdisk utility usb (use clover), boot to Mavericks partition (it will boot fine ). after that do the post install. for me this is the longest time i need to configure: how to boot without the bootdisk utility. since i never got to osx environment with chameleon, so clover is the one for my laptop. took some time to read about clover, and voilaa.. OSX Mavericks and Windows 8.1 Pro living living happily in my laptop.
it maybe not the "clean" way for dual booting (i try using grub, bcdedit, etc, never work ), but atleast it's working fine for me.
hope that helps.
