Installation constantly rebooting

[newbyr]

I installed OVOS on a Microsoft System 3 (!) which already had a Linux Mint install successfully running. All went well on the install and it worked fine.
Now, after restarting the system, it is in a constant rebooting loop. The linux Mint is up and fine, but it loads OVOS, which opens the screen with logo OVOS and the blue spinning loader symbol, but the spinner does 4 loops and then it crashes and restarts OVOS.
I can't even get to the Mint as the reboot keeps interrupting any action ! It's difficult even to just turn the Surface off !

Help please, to either fix, or kill OVOS booting long enough just to either test it or remove it.
Thank

It looks like OVOS is auto-starting and crashing in a loop, while Linux Mint itself is actually fine.

First thing to do is stop OVOS from starting automatically, so you can regain control of the system.

Try this first:
During boot, hold Shift or press Esc repeatedly to bring up the GRUB menu, then choose Linux Mint (or Advanced options → recovery).
If you can get into Mint, OVOS is the problem, not the OS.

If the GUI keeps looping, try switching to a terminal:
Press Ctrl + Alt + F2 (or F3/F4), log in, and disable OVOS services:

sudo systemctl disable ovos-gui
sudo systemctl disable ovos-shell
sudo systemctl disable ovos
sudo reboot

That should stop OVOS from launching and let Mint boot normally.

If you want to remove OVOS completely:

sudo apt remove ovos-shell ovos-gui ovos-core
sudo apt autoremove

If you want to debug instead, the 4-spin crash loop is usually a GPU / Wayland issue (common on Microsoft Surface devices).
You can check logs with:

journalctl -xe | grep ovos

or:

systemctl status ovos-gui

In short: Mint isn’t broken OVOS GUI is crashing and restarting. Disable its autostart first, then decide whether to fix or remove it.
