Problem loading UEFI:db

Post by Silvock » Wed Aug 22, 2018 6:00 pm

Hi,

I added a new ssd to my computer. I cloned the older which contained LM 18.3 and Win 10 then I installed a clean install of LM 19 on it.
LM 19 worked like a charm, I tried Win 10 and when I wanted to boot on LM 18.3 I had this :

Code: Select all

Problem loading UEFI:db X.509 certificate (-65)
nouveau 0000:01:00.0: DRM failed to create kernel channel, -22

BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu3) built-in shell (ash)

Initramfs
I’ve the same error with LM19 and I’m only able to boot on win 10.

I don’t know how to repair it.

Go in the firmware interface (/BIOS) and disable secure boot.
How to do that depends on the machine, here you can see some examples : http://www.rodsbooks.com/efi-bootloader ... ml#disable

Secure boot is already disabled. All OS are on UEFI boot mode. The live usb boot, sudo Os-prober on live-usb returns all Operating systems, sudo grub-update doesn’t work.
When I try to change the boot devices order and I set LM18.3 in first, I haven’t got the grub menu but directly grub command line. There are two versions of grub on each ssd.

Same hardware here https://forums.fedoraforum.org/showthre ... cate-(-65)

1.In firmware interface I’ve « Clear secure boot keys » option. It could be a solution ?
2.Maybe I should replace LM 19 by a fresh install of LM 18.3 hoping I can boot on the older LM 18.3 to reach my datas. https://www.forum-francophone-linuxmint ... 20&t=10327
3. Maybe I should do this :

Code: Select all

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of nvme0n1p2, using the following options:        nvme0n1p1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file

I applied Boot-repair recommendations and it worked !

I'm now able to boot on LM 19 and Win 10. However with LM 18.3 I'm still stuck with :

Code: Select all

BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs)

got a new DELL XPS 8500 with Windows 8. I understand that it has UEFI (as opposed to traditional boot-loading BIOS system). I installed Ubuntu 12.04 (not realizing that it doesn't work as well with the secure-load/uefi system). I partitioned my solid state drive so Windows was on one partition, and Ubuntu would be on a new one (sdb7). This always worked with my PREVIOUS computer... I had Windows XP on one partition and UbuntuStudio on a separate partition. Grub always gave me a boot menu.

I would advise starting a new thread, it's always less confusing and may attract more attention. It's also a rule on this forum.
