Hi Mika,

Re: [Bug 1734147] Re: Ubuntu 17.10 corrupting BIOS - many LENOVO laptops models
Hello Anthony, My situation is: Lenovo Ideapad Flex 10. Came with windows 8 installed and updated to windows 10. I then installed Ubuntu 14.04 as dual boot and had each release of Ubuntu updated since 14.04. I was dual booting using legacy for Ubuntu and UEFI for occasional access to windows 10. Only recent change has been upgrade to version 17.10. I can no longer save changes to the boot order in the BIOS. I cannot therefore boot from USB and am not able to boot into windows. I can boot into 17.10. The trigger for this problem arising was clearly the upgrade from 17.04 to 17.10. I also have a Lenovo G710 with Xubuntu installed and no other OS. It is booting using "Legacy". I have also upgraded this from 17.04 to 17.10 and do not have a problem with the BIOS on this laptop. I live in Cologne, Germany but work away in Mainz-Kastel, Germany during the week. My telephone number is 00491713568623.

All of this appears to point to a firmware implementation that does not conform to the EFI standard. If Ubuntu is doing something "wrong" here, it is very difficult to discern what it is. In the past, we have seen problems with the Linux kernel filling up the firmware's available nvram space and as a result causing boot problems. This could be another instance of that problem, but that doesn't seem to fit with the idea of efibootmgr successfully allowing boot entries to be deleted. -- 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
