I am not an expert in GRUB or EFI, but what it sounds like to me is that the initrd for the systems you are using does not have EFI support. Personally, I never use initrd but build my own kernels with all capabilities needed built in (not modules). You can test this by building your own kernel and ensure EFI_PARTITION is built in during the configure phase. -> File systems -> Partition Types -> Advanced partition selection (PARTITION_ADVANCED [=y]) Then if the kernel image is, say, /boot/linux-2.6.37, an entry in boot.cfg like: menuentry "My test kernel" { set root=(hd0,) linux /boot/linux-2.6.37 root=/dev/ ro } would be all that's needed. That may not be your final answer, but if it does boot, then GRUB is doing it's job and the problem is in the distro you are using. -- Bruce
