Fix the Grub issue with Windows 8 UEFI after installing Fedora 20

Posted on Mar 24, 2018 by Eric Ma In QA

Grub fails to boot with Windows 8 UEFI after installing Fedora 20. The Grub entry for Windows 8 is:

menuentry 'Windows Boot Manager' {
      chainloader /EFI/Microsoft/Boot/bootmgfw.efi
      boot
}

How to fix it?

The set root= is missing. You probably can fix this by specifying the root manually:

menuentry 'Windows Boot Manager' {
      insmod part_gpt
      set root='hd0,gpt2'
      chainloader /EFI/Microsoft/Boot/bootmgfw.efi
      boot
}
