Happy New Year! Acer Aspire E3-111-P605 with Insyde BIOS in legacy mode when updated to lubuntu 17.10 resulting in the problem unable to boot from USB or save changes in the BIOS.
My solution was to upgrade the kernel to 4.14.10. Still unable to make any changes in BIOS. However when booting GRUB2 and selecting "c" (entering prompt) and then "exit" the Intel Undi PXE -2.1 (build 083)utility was invoked and wait for the PXE utility to exit - then I could boot from USB and/or USB CD-ROM drives. I found it interesting that when booting if I pressed "ESC" the attached drives appeared on the BIOS info screen - however if I entered the BIOS with "F2" - the BIOS reported only the Hard Drive and the Intel PXE as available boot devices. -- 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/linux/+bug/1734147/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
