Yes. http://www.tonymacx86.com/multi-booting/96000-guide-dual-booting-mountain-lion-windows-8-a.html
Works with Chimera if Win8 was installed Non-EFI legacy mode, works with Clover if Win8 was installed UEFI. To check, look at drive with the disk management tool - if it has an EFI partition labeled WinRE Tools and a revovery partition, then it is UEFI. If it just shows a System Reserved partition it was installed legacy mode.
