Title:
Ubuntu 17.10 corrupting BIOS - many LENOVO laptops models
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Artful:
Confirmed
Bug description:
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!!
