[ubuntu-uk] error: invalid arch independent ELF magic

[James Morrissey]

Hi,

I am having a problem installing 11.10.

Install seems to go fine but when i try and boot i get:

error: invalid arch independent ELF magic
grub rescue >

I think it has to do with this being a thinkpad and having UEFI.
Apparently i need to install grub-efi while on the live CD
(http://askubuntu.com/questions/37692/grub-invalid-arch-independent-elf-magic-after-natty-install-on-ssd)
but don't really know what to do.

If anyone would help with some handholding i would appreciate it.

Thanks

james
