Well, you could try changing UEFI to Legacy and see if that works... But Before You Do That...
Try launching gparted in the LiveUSB of Zorin OS.
Select the partition you wish to install Zorin OS to.
Click the (-) icon to delete it.
Click the newly created free space.
Click the (+) button to add formatting to that free space.
Format the partition in ext4.
Once formatting is complete, then launch the Zorin OS Installer from the desktop icon.
See if it runs through...
There are two fast boots in a system with windows. One is in the bios. The other is implemented by windows. You can use Before You Install to remove windows fast boot, which locks the drive from change by anything other than windows.
What is the worst that could happen? You wipe your drive and windows is no longer there. Though it's not an ideal consequence, it is not the end. It doesn't "brick" your computer (very little will). It would mean having to reinstall windows.
Taking your time, following the tutorial and asking questions help you achieve what you want, learn and become confident.
Just make sure you backup any personal data before you begin.
There is no need to be anxious or fear any particular outcome. There is an entire community here that would be willing to help you through any difficulties.

Also look into VMD as another choice.
