Please write on a paper the following URL:
http://paste.ubuntu.com/p/vdgzmJWBHC/
In case you still experience boot problem, indicate this URL to:
[email protected] or to your favorite support forum.
You can now reboot your computer.
Please do not forget to make your BIOS boot on nvme0n1p1/EFI/ubuntu/shimx64.efi file!
If your computer reboots directly into Windows, try to change the boot order in your BIOS.
If your BIOS does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi
