I'm using refind to dual boot windows and chromeos on a macmini 8,1.

The broadcom wifi is not working. The hardware Ids from Windows look like this,

PCI\VEN_14E4&DEV_4464&SUBSYS_07BF106B&REV_03 PCI\VEN_14E4&DEV_4464&SUBSYS_07BF106B PCI\VEN_14E4&DEV_4464&CC_028000 PCI\VEN_14E4&DEV_4464&CC_0280

There is a great article on the wiki on it. ChromeOS makes it harder to load FW drivers. Go to the Wiki tab and check the Wifi section under “Install on a Mac”
