Lenovo X220 wont boot.

[Peter Ankerstål]

Hi,


I just got a Lenovo X220, a one with a i7-2640M CPU. I can boot from cd 
and install the OS without any problem, but when im going to boot the 
system
for the first time it just stops and give me a menu to choose boot-order 
(bios). I figured out that this has something to to with the EFI on this 
machine and
tried to disable EFI-boot and only use legacy, but I still have the same 
problem. Does anyone of you have any pointers here?

Best
Peter.
