Infiltrator Posted July 9, 2013 Share Posted July 9, 2013 (edited) Windows 8 is UEFI certified. Fedora isn't. That's why when you disable UEFI, you can boot your Fedora distribution. And when you enable UEFI, only Windows 8 is able to boot. http://docs.fedoraproject.org/en-US/Fedora/18/html-single/UEFI_Secure_Boot_Guide/index.html Edited July 9, 2013 by Infiltrator Quote Link to comment Share on other sites More sharing options...

Now, i have a little progress so when i enable UEFI boot still use GRUB but i can't boot to windows 8, but when i disable UEFI boot still use GRUB but now i can boot to windows 8. Now, there is new problem when i can boot to windows 8, it is not show login interface but boot repair wizard for windows 8. Have any solution?

barry99705 Posted July 9, 2013 Share Posted July 9, 2013 Most likely windows 8 is seeing grub and trying to remove it. That's why you get the repair wizard. Quote Link to comment Share on other sites More sharing options...
