5. If you have Zorin on a USB drive and cannot boot into it (assuming you changed boot order in BIOS):
   a. Confirm that the USB drive is working properly.
   b. Check any cables used to connect to the drive.
   c. Use another computer or USB drive.

Finally, you can try Balena alternatives like Unetbootin and Rufus.

Most of the time, an installation problem is due to one of the following:

1. bad download.
2. bad media (USB/DVD).
3. need to change a BIOS setting.
