Thunderbolt must be plugged in to boot Zorin OS

In order to boot zorin OS thunderbold must be plugged. Whithout it stills stuck to the zorin logo .
Asking for help please

It may need the Network or HDMI connection that Thunderbolt is providing. Do you have an External Monitor connected? If so, we should look at terminal output of

sudo lshw -C video

If not an external monitor, then it may be relying on your Ethernet connection. If there is another hardware service provided by Thunderbolt, please suggest it as well.

I'm connecting anything to the thunderbolt. normally I can connect an ethernet cable , an hdmi cable for a monitor and I have an additional usb port.

Do you mean to say not connecting anything?

yes. and after booting I can unblug the thunderbolt without an issue

Hopefully other members may weigh in - I must leave the computer for a while.

sudo nano /etc/default/grub

Arrow Key down to this line:

# Uncomment to disable graphical terminal (grub-pc only)

Uncomment the #GRUB_TERMINAL=console line so that it now looks exactly like:

# Uncomment to disable graphical terminal (grub-pc only)

Tap ctrl+o to overwrite, then enter key to save, then ctrl+x to exit the editor.
Now, you must update grub in order for the changes to take effect. Run:

sudo update-grub

Reboot and test...

I still have the same problem. It works when I plug anything on the usb-c port not only the thunderbolt.

Looks like a kernel issue for someone else.. I'm not sure how to diagnose though. I would think maybe something with PXE boot? Seems like it's trying to probe hardware through those ports; for what, beyond me. Maybe a legacy USB setting? This is very intriguing.. Have you looked through BIOS for anything odd in your boot order?

Hello, Everything is ok with the boot order. This is what I have when I don't have something plugged in the usb-c port.

This is very strange. The ACPI errors relate to the ACPI tables (Motherboard /hardware) and should be present whether you have anything plugged into the USB-C port or not.
As you can see on the timestamps for the ACPI errors, they are very close together prior to initialization of graphics or essential drivers. So they are not causing No Boot.

I did find a bug report on the 5.15 kernel that details this issue.
Let's try upgrading your kernel and drivers:

sudo add-apt-repository ppa:tuxinvader/lts-mainline

sudo apt update

sudo apt install linux-generic-6.02

Once installed, reboot and test without and with something plugged into USB-C port.
