Do you have a USB to sdcard adapter? That is what I used that worked.
Go back to the instructions, you use the Unetbootin USB to make a second USB using instructions on p9 post 6.
The menu.lst and save folder need to be copied from your sdcard master to the new 2nd USB
You boot from the new 2nd USB to create the sdcard using instructions above, but may have to have a USB to sdcard adapter.
Here's an alternate method, maybe some clicks missing since I was in a hurry.
Rescueszilla method
You will need:
-rescuezilla USB
-USB to store the image
-sdcard configured as your Cloudpup master
-download rescuezilla ISO and create USB https://rescuezilla.com/download
-insert all 3 devices above
-boot rescuezilla
-click Backup
-choose sdcard
-store image on 2nd USB
When complete remove master sd
-insert new sd
-click Restore
-select image location
-select image
-click Next
-select the target
-click next
When the restore is complete you may have to resize the sd using gparted (included on rescuezilla)
