We made a fresh 18.04 LTS Lubuntu 64 bits install + updates on Acer TravelMate B118-M (2019), booting with Secure Boot Disabled. Ok!
We clone this installation to Acer TravelMate B117-M (2018, 2017), booting with Legacy mode. We had the problem. We can boot ours B117-M pressing Esc at boot. And we found as workaround: sudo su rm -R /boot/efi/EFI/BOOT reboot After that, we made the same change to the original (B118-M) and we booted without problems. So, it seems like /boot/efi/EFI/BOOT folder is the cause of the problem. Machines are booting correctly from /boot/efi/EFI/ubuntu folder. We have the rest of ours B117-M with 16.04 LTS. The folder BOOT doesn't exist on 16.04 installations. efibootmgr outputs at: https://drive.google.com/drive/folders/1IM0DAxhKIQphl8fWp13xIFhIvHKwr72_ ** Attachment added: "efibootmgr_bm117-m_18.04_with_problems.jpg" https://bugs.launchpad.net/ubuntu/+bug/1835639/+attachment/5296615/+files/efibootmgr_bm117-m_18.04_with_problems.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1835639 Title: During boot - System bootorder not found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1835639/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
