Salutations, In these cases, I usually whip out a copy of refind-efi on cd and boot that via uefi. Refind-efi now detects kernels in /boot so it may be able to detect the Arch and Ubuntu kernels. This would allow you to boot the kernels into uefi mode and run efibootmgr. Regards, Mark -----Original Message----- From: "Alan E.

I installed gummiboot on /boot, where the kernel was. But I didn't move the ubuntu kernel over. In the end, Windows still booted, and I was able to get back to a boot menu from there, and boot ubuntu. Not Arch. Yet. Thank you for now.

Salutations,
You need to boot into UEFI mode. So when you're loading the Arch Linux ISO, make sure you select to boot into UEFI mode (usually an option in the boot menu)

You can do this without being booted into EFI mode, since gummiboot will install itself as /boot/EFI/Boot/BOOTX64.EFI and then you can set it up properly after the first boot.
I had to do it this way because my hardware (T530) ran into the EFISTUB bug on old kernel versions, including the latest Arch ISO. It's completely fixed now at least on this hardware... no issues with dozens of 3.14.1/3.14.2 builds or the latest LTS kernel.
