Sounds like your system is messed up. Just restore the backup you created before executing such a critical task, where, of course, obviously, such a backup is mandatory. 
Sorry to say, I didn’t took any backup before that. I didn’t thought of something like this 
Sorry for this issue.
Historically, windows DEMANDS to be installed first.
If you have another HDD or can acquire one, it would be possible for you to install windows first and then your Zorin OS.
After ensuring full functionality, you could copy files from the current drive to wherever you want on the new drive.
