I run a quad-boot with Fedora, Ubuntu, ChromiumOS, and Windows 8. I have discovered that Windows 8 will no longer hibernate - it just brings me back to the lock screen. When I run it from command-line, I get this:

The problem is, Windows also can't do it's fast-startup thing because that involves kernel hibernation. The only way I can shutdown is with shutdown /s /t 0 or a shortcut that invokes it.
Apparently, this problem is tied to Windows having its boot manager in control. That's great, but if I hibernate Windows, its boot manager won't let me start up anything else, defeating the whole point of a multiboot. Using GRUB, you can hibernate an OS and start up another, then come back to the other one.
How can I keep my multiboot and also be able to hibernate Windows 8?
powercfg -h onto (re)enable hybernation. Does that return any error? – K.A.Monica Jan 06 '13 at 17:43doesn't work in comments, use backticks instead.)– WindowsEscapist Jan 06 '13 at 19:08
