[Bug 1565674] Re: when install ubuntu 16.04 beta 2 after window 8.1 (dual boot) , Grub installation failed.Show message is " The grub-efi-amd64-signed package failed to install into /terget

[Phillip Susi]

You are trying to install in EFI mode but your disk is not set up for
it.  You ignored the warning message and tried to continue in EFI mode
instead of switching to bios mode.


** Changed in: grub-installer (Ubuntu)
       Status: Confirmed => Invalid
