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.

For example:
