Same problem on Dell Inspiron 3593 with dual boot Windows 10 and Ubuntu 18.04. As Johann Gail writes, this was previously working without problem until a few weeks ago.
I have not tried the tpm fix. I have tried changing boot order, enabling/disabling secure boot - neither of these appear to solve the problem. Typing "reboot" at the grub prompt sometimes works immediately, other times I need to reboot again before booting successfully. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883785 Title: intermittent boot failure dell inspiron 3593 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1883785/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
