Unable to boot installer

[Cybil Courraud]

Hi Daniel,
it seems that there is a problem with UEFI/atkbd, since 7.2 and 8.0 work 
without any boot problem (BTW that's not a solution because there is no 
NIC support) and 8.1 and 8.2 hang.

I met the same problem with my x220 which is not resolved but you can 
follow this workaround:

1 - Plug an external USB keyboard
2 - boot with a memstick with 8.2
3 - In the loader:
     set hint.atkbd.0.disabled=1
     boot
4 - Follow install via network or other
5 - Setup BIOS: Config > USB UEFI BIOS > disabled
6 - reboot

You could try with a CD, directly without UEFI, it may work as is (I 
didn't burn it for the exercise).

That's what worked for me.
