My pleasure...
You may need to use an earlier kernel than the current kernel used by Zorin. This method allows you to set the kernel that you will boot into by default.
To set the new kernel to default:
Boot into the kernel you wish to be Saved.
Open terminal and run:
sudo nano /etc/default/grub
Change GRUB_DEFAULT=0 to GRUB_DEFAULT=saved
Hit enter to drop down a line.
Add GRUB_SAVEDEFAULT=true
ctrl+x to exit, then the y key to say yes to save, then the enter key to save as current configuration.
