Not a lot of terminal work is required on this, really.
Firs things first, check the integrity of the Windows Drive. Look for bad sectors.
Next:: DEFRAG. Thoroughly. NTFS fragments badly and if trying to secure or move a partition, this can really cause problems. Defrag until it will defrag no more.
Once done, you can open your Windows Partition Manager and create a partition for Zorin - you can even preemptively format it to ext4, if you want. I cannot (effectively) write a guide on using the Windows Partition Manager as I do not use it... But it may be more familiar to you than the Linux Equivalent Gparted is.
We can use Gparted, too, if you prefer. It is really, really easy to use.
Once all that is done, boot the LiveUSB of Zorin OS.
Connect to the net and run the installer. Check to ON for downloading third party drivers, etc and the additional updates as you go.
Monitor the installation. If it gets stuck, then try again with the checkmark OFF for third party drives and not connected to the net.
If still no good, we may need to check some BIOS settings.
