Adding a menuentry to grub will boot Windows 8 using Grub2 and Secure Boot. In /etc/grub.d/40_custom, put the following lines: menuentry 'Windows 8.1 (loader) (on /dev/sda14)' { echo "Loading Windows 8.1" insmod part_gpt insmod fat insmod search_fs_uuid insmod chain search --fs-uuid --set=root --hint-bios=hd0,gpt2 --hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2 44ED-7819 chainloader (${root})/EFI/Microsoft/Boot/bootmgfw.efi } Notice: "44ED-7819" should be replaced by your own uid of efi partition.
