** Description changed: + =====[Edit July 2nd, 08:06UTC]===== + + Trying to boot from a 18.04.2 live USB or 19.04 live USB exhibits the + same kind of issue, no matter if Secure Boot is enabled or not in the + BIOS. + + No matter Secure Boot is enabled or not in the BIOS, I briefly see + "Booting in insecure mode", then "error: file /boot/ not found" before + showing GRUB menu. + + I tried the 16.04 OEM image and it works reliably. I can install it and + once installed, I can boot into the system 10 times out of 10. + + =====[Original Description]===== + Device: Dell Inspiron 7370 BIOS: 1.2.0 This device was certified with 16.04: https://certification.ubuntu.com/hardware/201704-25503/ I installed Ubuntu 19.04 and although it installed properly, about 50% of the time, the device won't boot at all. I need to shut it down and restart it. Steps to reproduce ------------------ In the BIOS, make sure - SATA mode is set to AHCI - Secure Boot is enabled 1. Install Ubuntu 19.04 stock. I selected the following options: - Erase disk and install Ubuntu - Full disk encryption - Minimal install - Install 3rd party drivers (this requires to enroll MOK key at the next reboot using a password) 2. After installation, boot into Ubuntu. Expected results ---------------- The device boots up Ubuntu reliably. Actual results -------------- About 50% of the time, the screen remains dark purple and nohting moves. I have to manually shut it down and re-start it until it ends up booting Ubuntu. It looks like it stops at step: "Loading initial ramdisk..." Failure rate ------------ I booted 22 times. It failed to boot 13 times and booted up properly 9 times. -> failure rate = 59 % ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: linux-image-5.0.0-20-generic 5.0.0-20.21 ProcVersionSignature: Ubuntu 5.0.0-20.21-generic 5.0.8 Uname: Linux 5.0.0-20-generic x86_64 ApportVersion: 2.20.10-0ubuntu27 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: pieq 1846 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC0: pieq 1846 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Mon Jul 1 17:38:59 2019 InstallationDate: Installed on 2019-07-01 (0 days ago) InstallationMedia: Ubuntu 19.04 "Disco Dingo" - Release amd64 (20190416) Lsusb: - Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub - Bus 001 Device 003: ID 8087:0a2a Intel Corp. - Bus 001 Device 002: ID 0bda:58f5 Realtek Semiconductor Corp. - Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub + Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub + Bus 001 Device 003: ID 8087:0a2a Intel Corp. + Bus 001 Device 002: ID 0bda:58f5 Realtek Semiconductor Corp. + Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub MachineType: Dell Inc.
