Fixing Windows 8 and Mountain Lion Dual-boot Issues

Recommended Posts

I can't seem to get Chameleon working no matter what I do. I tried setting my OS X partition to active in Windows using diskpart using list disk select disk x list partition select partition x active exit exit, but that didnt seem to load chameleon, even after i reinstalled chameleon. then i tried setting it to active in OS X using diskpart list fdisk e dev rdiskx f x write y exit exit, and that didnt work. then i tried turning windows 8 fast restart off, and that didnt work. im out of ideas.

I use GParted on a live cd to set the OSX partition flag to boot, I'm not sure why diskpart's active command doesn't do the same thing.

Give it a try, works for me.

Weirdest thing. I reset everything in the bios to default, flipped the power switch on the power supply and restarted. Chameleon now works. Does this have anything to do with whatever UEFI is?
