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

I agree with you, Lenovo has nothing to do with this issue, however I
think it's Ubuntu devs responsability to take a look and try to fix this
issue, since Ubuntu 17.10 has corrupted our bios. Our machines here
(different models) reported this issue only after installing Ubuntu
17.10 and if you browse this forum, you would see that many others
reported Ubuntu corrupting the BIOS, something that is extremely
serious.

** Description changed:

  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:
