A message to the developers. The situation in my case is the following:
Many identical laptops in a private educational institution, (Lenovo G40-30), running Windows 10 (64bit) and Lubuntu 17.04 (64bit) in LEGACY Mode, without any problems. A few days ago, we decided to install Ubuntu 17.10 on the laptops, replacing Lubuntu 17.04. Immediately after the installation of 17.10, the BIOS failed to save settings and the option to boot from USB stopped showing up. Time and date are correct and have not been affected. We have tried 35 different USB flash drives, created with every software available, as well as dd via command line to check whether USB boot would work, but it didn't. Neither secure boot nor fast boot is enabled. Lenovo's bios upgrade tool does not work, as the computers simply restart when we run the executable from Windows. Regarding your comment that the Fall Creators Update might have caused the problem, that cannot be right, as this was performed quite a few weeks ago, and the BIOS worked fine after the completion of the update. We contacted the technical support of Lenovo in Greece, They stated that Linux is not officially supported by Lenovo, so there is not much they can do about it. Yet, they agreed to contact their headquarters to notify them about the problem and request a solution. They clearly stated that the BIOS malfunction might be resolved by replacing the motherboards. If neither Ubuntu nor Lenovo can help us, what should we do? Throw away the laptops that have been affected, simply because we decided to use a newer version of Ubuntu? The laptops worked fine until the moment Ubuntu 17.10 was installed. Please try to have a look at it and do let us know what information you need from us in order to help us resolve this extremely serious problem which has bricked our devices' bios. Please let me repeat that the problem occurred right after the installation of Ubuntu 17.10 in Legacy mode. Thank you in advance for your time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1734147 Title: Ubuntu 17.10 corrupting BIOS - many LENOVO laptops models To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1734147/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
