> Hi all,
>
> Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
> reported a corrupted BIOS.
>
> It's not possible to save new settings in BIOS anymore and after
> rebooting, the system starts with the old settings.
>
> Moreover (and most important) USB booting is not possible anymore
> since USB is not recognized. It's very serious, since our machines do
> not have a CDROM.
>
> Lenovo forums at the moment are full of topics regading this issue.

> Thank you!!
