Ubuntu – How to boot linux from a EFI partition on a USB drive

grubrescueinstallationmacserveruefi

I managed to create a USB drive image for booting with EFI using Mac-Linux-USB-Loader(issue).

The directory structure is as shown here.

F:\>tree /f
Folder PATH listing for volume NEW VOLUME
Volume serial number is 9478-C771
F:.
└───efi
    └───boot
            bootX64.efi
            boot.iso

boot.iso is ~689MB and bootX64.efi is ~600KB.

While attempting to boot, I end up in the grub shell. I video recorded my screen and have some screen shots here.

How do I proceed booting? I care more to install linux on my mac mini (late 2012) than to fix this issue. I will be happy to boor boot manually and start the installer. I am installing ubuntu-13.10-server-amd64+mac.iso

The following worked for me.

grub> kernel (hd1,gpt2)\vmlinuz-3.11.0-13-generic root=/dev/sdb3
grub> initd (hd1,gpt2)\initrd-3.11.0-13-generic
grub> boot
