As I mentioned before, I have encountered the exact same problem. Everything was fine and dandy until I installed the Ubuntu 17.10. I installed multiple Linux distributions on my machine in the past and everything was working as expected every single time. As soon as I installed the Ubuntu 17.10 my laptop firmware had the exact same symptoms. Lenovo service replaced my laptop’s motherboard and updated the firmware. After that, I tried to install the Ubuntu 17.10 one more time. And again my laptop’s firmware got broken. Fortunately, Lenovo service replaced the motherboard.
Now I use Windows 10 with the Fall Creators Update and UEFI works as expected. After two motherboard replacements I do not want to risk installing Ubuntu again but I imagine that my laptop’s firmware will get corrupted again. Maybe it is Lenovo’s fault for shipping laptops with broken firmware "by design". However, that does not explain why other Linux distributions (including the old versions of Ubuntu) was working fine. -- 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
