[SOLVED] Manually Adding Windows to Gummiboot

When I was installing gummiboot and setting up Arch for the first time, I created an EFI system partiton dedicated soley to gummiboot, so I'm assuming this is why gummiboot is not detecting Windows by default. I was unsure if the 100 MB provided by the Windows EFI partition would be enough, as the wiki recommended 1 GB. How would I create an entry to allow me to boot Windows?

You can try copying over the \EFI\Microsoft folder on the Windows EFI system partition to /boot/EFI/Microsoft on your Arch system's ESP but I really don't know if that would work.

I think the better solution would be to copy the entire /boot folder over to the Windows ESP and change the mount point in /etc/fstab -- gummiboot will then provide a menu entry for Windows automatically.

You should always share the Windows-generated ESP with your Arch system, if possible.

Don't have multiple $esp, just use the windows one. 100MiB is more than enough for arch + windows.

/dev/sda2        256M    60M  197M  24% /boot/efi

I have Arch, Slackware and Windows 8 (and grub). You're fine

Re: [SOLVED] Manually Adding Windows to Gummiboot

Oh, sorry. I just copied my /boot to a temporary location, uninstalled my boot loader, and changed the mount point of the EFI system partition in the fstab to the one Windows made. Then, I reinstalled my boot loader in the new location, and copied over the initramfs-linux.img, initramfs-linux-fallback.img, and vmlinuz-linux. After that, it worked fine for me.
