Ubuntu server 11.04 amd64 does not detect uefi

Bug Description

Binary package hint: grub-installer

Installed Ubuntu server 11.04 amd64 on an Intel D510MO with Uefi enabled on a 2TB harddisk, no boot.

The installer installs grub-pc in the last stage of the installation. Because the disc is to big for regular boot it will be unbootable even after disabling UEFI.

Are there suggested work arounds or parameters I can give te installer to force installation of grub-EFI?

disc layout:
1 mb grub
1,98 TB / btrfs
2 GB swap

Work around, upgrading to bios 0524 on the Intel 510MO made me able to boot the 2TB drive in non-uefi mode. It hangs on uefi install.

This bug report seems to rest on a misconception. You don't need grub-efi to use a GPT partition table; even though GPT is part of the UEFI specification, it's perfectly possible to use it with grub-pc.

And no, there is no way to force the installer to install grub-efi on a BIOS system; it wouldn't work! The boot loader image you use has to match the *firmware*, not the partition table type.

Sorry for the misconception. I'm now able to boot from the the 2TB hdd if I use the mainboard in non UEFI mode (bios emulation). 11.04 server installer hangs on uefi mode. (since the firmware/bios update 0524)

I get a menu now (since update, before it stayed blank) when I run the installer in UEFI mode, but after that it won't boot. If I read the changelog correctly for the kernel this seems to be a fixed kernel issue on <3.0 kernels.

The boot issue is still a work around because the installer won't boot in uefi (maybe usb installer issue). It won't boot UEFI after the installation either, because it detects the BIOS emulation during the install.
