grub2 EFI boot loader internal/external booting

[bean123]

Thanks bean. I tried the noefi option -- with the following line:

linux /install/vmlinuz video=efifb noefi

No luck -- after loading the initrd.gz, and issuing the boot command, the machine hangs.

"About rEFIt" gives the following information:

EFI Version: 1.1
Platform: x86_64 (64 bit)
Firmware: Apple 1.10
Screen Output: Graphics Output (UEFI), 1024x768

Are the different versions of "burg" you've posted dependent on a particular kernel version?

No, it doesn't depend on kernel. But some kernel has bugs that may hang without the noefi option. Perhaps this is some new issue regarding 10.04 release, I'd test it on my mac soon.

So it might be worthwhile to try Karmic (9.10) then?

I'll give that a try.

No luck booting Karmic (9.10) with the following menuentry:

menuentry "Ubuntu Server 9.10 installer cd" {
fakebios
root=cd0
linux /install/vmlinuz video=efifb noefi
initrd /install/initrd.gz
}

the kernel loads as does the initrd.gz.

the system hangs when the 'boot' command is issued.

BTW, do you have more than 4G memory ?

[engelsma]

The machine is currently configured with 3 GB of RAM (base configuration).

You can try the amd64 version as well. The EFI firmware is 64-bit, it works better with a 64-bit kernel. It may even work without fakebios and the noefi option.

If it still fails, try debian 5.0 amd64.

I assume you are referring to using the amd64 versions of Ubuntu, correct? That's what I've been using -- 64 bit ubuntu server. I haven't tried any 32-bit versions.

I'll try booting with no options and see what happens. Next, I'll try Debian.

Thanks bean -- the Debian 5.0.4 Net Install ISO (amd64 platform) boots with:

fakebios
root=cd0
linux /install.amd/vmlinuz video=efifb
initrd /install.amd/initrd.gz

The kernel messages scroll by and I get the initial "Choose Language" screen from the Debian installer.

I'm going to try the Ubuntu 10.04 amd64 mini ISO installer with the same options.

[engelsma]

The Ubuntu 10.04 amd64 mini.iso does not boot.

Tried the same options as with the Debian net install CD... the kernel and initrd.gz load, then the system hangs when executing the 'boot' command. No kernel messages or anything...

Is my only option to install Debian? I was really hoping for Ubuntu Server...

You can use debian for the time being. Ubuntu is based on debian, most package is available in both ubuntu and debian. I'd test the ubuntu kernel when I have some spare time.
