I also did that with cloudready, still have it on the thumb drive. Never use it though.
But must say runs super smooth. No problems what so ever.

Boot chrome os drive partition change and I can't found my files

I also have ChromeOS (cloudready) installed on a usb (64gb) the partitions looks like this. [Screenshot from 2021-10-23 17-10-57] But when I do this it formats the usb and then installs ChromeOS. Try using gparted look if you can find the Zorin partitions, if not then I'm afraid they have been formatted. You then will have to format the partition and reinstall Zorin.
