[Bug 1734147] Re: Ubuntu 17.10 corrupting BIOS - many LENOVO laptops models

[britgreek]

Actually, this MUST be a Ubuntu / Linux bug, as the current Ubuntu 17.10
rendered our Lenovo laptops useless in the long run, without any
documentation or warning that the installation would affect the BIOS.
This is a very serious issue, both legally and ethically and I think
that we should demand an immediate fix. No OS should have anything to do
with the modification of the BIOS without the consent of the owner. What
will happen if we need to format our hard drives? How will we be able to
install the OS that we want? i am not happy with any workaround. I want
my computer to function as it did when I purchased it, in terms of its
bios settings and booting from USB is an essential feature. What remains
to be explained is the reason why it only affects Lenovo hardware and
not any other brand.

Title:
  Ubuntu 17.10 corrupting BIOS - many LENOVO laptops models

Status in grub2 package in Ubuntu:
  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.

  For example:

  -Save-Settings-or-boot-with-USB/m-p/3849142
