My Situation is the following:

I want to install Ubuntu jammy jellyfish 22.04 LTS instead of manjaro on my laptop. The laptop already had a working dual boot and so I thought replacing one Linux-system with another should not be a big problem.

While the Installation of jammy jellyfish seemed to succed, after restarting the laptop it ends up in a loop.

First it shows the normal screen it always shows before grub menu. It is a screen with some hardwaredata and the reminder to press F1 for a Bios menu.

Then it shows one mostly black screen and a message that disapers too fast to read.

After that there is another message saying "Reset system". Then it goes back to the first screen.

I can enter a menu in which there is the possiblity to choose bootmanager. If I choose "Windows 11" windows 11 starts normally. If I choose the other option begining with SAMSUNG (disk is SAMSUNG MZVLB256HBHQ-000L7(nvme)) I end up in the loop again.

Laptop: Lenovo Thinkpad T495

Earlier Installations: dual boot with Windows 11 and Manjaro KDE

Secure Boot: diabled

Istallation via: USB

Partition Table: gpt

Model SAMSUNG MZVLB256HBHQ-000L7(nvme)

I did enter
sudo efibootmgr -c -g -w -L "ubuntu" -l "EFIubuntushimx64.efi" -d /dev/nvme0n1 -p 1
while in "try Ubuntu"-mode.

The result was the following:

BootCurrent: 001B

Timeout: 0 seconds

BootOrder: 0001, 0016, 001B, 0017, 0018, 0019, 001A, 0000, 001C

Boot0000* Windows Boot Manager

Boot0010 Setup

Boot0011 Boot Menu

Boot0012 Diagnostic Splash Screen

Boot0013 Lenevo Diagnostics

Boot0014 Startup Interrupt Menu

Boot0015 Rescue and Recovery

Boot0016* USB CD

Boot0017* USB FDD

Boot0018* NVMe0

Boot0019* NVMe1

Boot001A* ATA HDD0

Boot001B* USB HDD

Boot001C* PCI LAN

Boot001D Regulatory Information

Boot001E* Boot Next Boot Option

Boot0001* ubuntu

In "Thinkpad setup -> Startup" (I think that is UEFI settings, I reached it by pressing f1 before booting) I get the following:

1 USB CD

2 USB HDD

3 USB FDD

4 NVMe0 SAMSUNG MZVL...

5 NVMe1

6 ATA HDD0

7 Windows Boot Manager

8 PCI LAN

there is no "ubuntu" entry

I tried to solve the problem by:

Installing with third party programs download enabled

Using the boot-repair tool: the tool ran for a long time, but there was no progress recognizable (even when I started it in debug mode)

You can find the report under https://paste.ubuntu.com/p/pWmbMzN959 (Also because of some other attempts to get the dual boot to work, nvme0n1p5 now is called nvme0n1p6)

Current report: https://paste.ubuntu.com/p/Wj6MJFSvbD

I let boot-repair tool run again, but it still didn't do anything.

Any help with this would be greatly appreciated.
