I have raid 0 set up on a system with Windows 8.1 and Ubuntu 14.04. I can boot to both just fine but I have to do it in the UEFI BIOS.

I would like to have in a boot menu in GRUB. Is that possible? I have tried a few workarounds with no luck.

In GRUB Customizer it does not show the UEFI Windows path at all. I tried some Windows based editors but it just corrupts the boot loader.

After I installed Ubuntu, it would not load I had to run Boot-Repair.

I have added my GRUB config file (/boot/grub/grub.cfg). I am not a expert, thanks.

  • When you boot to Linux, is there a directory called /sys/firmware/efi?

You're booting Linux in EFI mode, so I don't know why the GRUB configuration scripts aren't picking up the Windows boot loader. The fact that you can boot to Windows means that the Windows boot loader is present. I have two suggestions.

First, you could edit the /etc/grub.d/40_custom file. Create an entry that resembles the following:

menuentry "Windows 8.1" {
    insmod part_gpt
    insmod chain
    set root='(hd0,gpt1)'
    chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}

You may need to change (hd0,gpt1) to (hd0,gpt2) or some other value, though, depending on the partition number of your EFI System Partition (ESP). Once you've created that entry, type sudo update-grub to update your main GRUB configuration file. When you reboot and select Linux from the firmware's boot manager, Windows should appear as an option.

Another possibility is to try my rEFInd boot manager. I recommend doing this by first trying the CD-R or USB flash driver version, available on the program's downloads page. rEFInd should give you options for both Linux and Windows. If both work, then install the Debian package, which should then take over as your primary boot manager.
