Hello,
my last dom0 update failed round about 10 days before.
I have done no changes to bios settings, etc.
My backups are not useable.
I do use a Lenovo Thinkpad T15, Core i7 CPU with the following specs
Notebook type number: 20S6-003NGE
Production date 2021/01
UEFI Bios Version N2XET29W (1.19)
Machine Type Model 20S003NGE
CPU Type: Intel(R) Core™ i7-10510U
I can mount the luks partition with a live cd.
Main problems:
- Booting not possible.
- I cant find my actual Ubuntu container in the luks encrypted partition.
The first problem was, that I get a black boot screen, before the luks encryption password field appears:
Fixed by removing the quiet option from boot options (choosing e, for editing boot menu),
as described here:
https://forum.qubes-os.org/t/black-screen-after-blue-select-operating-system-screen/17425/5
The cursor needs 0,5 seconds to move from one letter to another, in the boot menu. Running an os from a live cd doesn`t show this behaviour.
The boot process hangs with the error message:
xen_acpi_processor: Uploading Xen processor PM info
The operating systems list to choose from, looks like this:
Xen hypervisor, version 4.14.5
Xen hyervisor, version 4.14.5.config
Submenu:
- Qubes, with Xen 4.14.5.config and Linux 5.15.94-1.qubes.fc32.x86_84
- Qubes, with Xen 4.14.5.config and Linux 5.15.89-1.qubes.fc32.x86_64
- Qubes, with Xen 4.14.5.config and Linux 5.15.81-1.fc32.qubes.x86_64
Whatever entry I choose to boot from, the error message is always the same:
Loading Xen 4,14,5 config …
error: no multiboot header found
Loading Linux 5.15.<$version-from-above-bulletpoints>
error: you need to load the kernel first
Loading initial ramdisk …
error: you need to load the kernel first
There is a forum post, that suggests, to check the bootloader for spelling mistakes and to check the multiboot segment in the linker.ld, but I dont know how to do so.
If I start the rescue shell from the usb installer, the output is:
Warning: /dev/root doesnt exist.

nvme nvme0: Missing or invalid SUBMQN field.
Can I just download the missing files from somewhere and make the appropriate adjustments, like adding the disk id, on one of the config files?
Thanks a ton in advance for hands on tipps.
This is how the boot folder structure looks like:
