Cannot boot vmlinuz in efi

[sspans]

I've solved this by using a memdisk to store the vmlinuz/initrd.
Sample script below:

Code:

# needed to build a custom bootloader
yum install grub2-efi-modules

mkdir -p boot/grub
cp grub.cfg boot/grub/
tar cvf memdisk.tar vmlinuz initrd.img boot
grub2-mkimage  -v --memdisk=memdisk.tar -o bootx64.efi -O x86_64-efi memdisk tar echo sleep linux linuxefi lsefi reboot multiboot linux16 boot efi_uga gfxterm
rm -rf memdisk.tar boot

And a grub.cfg like this:

Code:

menuentry "CentOS-6" {
    set gfxpayload=keep
    linux (memdisk)/vmlinuz ks=http://boot.mccm.mcinfra.net/install/centos-6/install.ks ksdevice=link
    initrd (memdisk)/initrd.img
}

set timeout=0
set default="CentOS-6"
