Not sure why you would want to make a boot drive out of an external hdd. Not sure that it is even possible for mere mortals.
But at this point the big question is whether or not you had any data on the freecom that was important to you. If so, and if you are perhaps not too savvy with this sort of thing, you may want to take the external hdd to a reputable computer shop to see if any of the data can be salvaged rather than trying to recover any data yourself.
If there was no important data on the external hdd to speak of, just go back through the steps to try to make the external hdd usable again as a storage device ONLY-- as it was intended. Also, use the software documentation instead of utube.
Chances are that you inadvertently checked off a box to make the drive "invisible". Either that or the OS on the primary drive is protecting itself by not looking directly at the Medusa you have created lest it be turned to stone. LOL
Messing with partitions can be a useful tool and is not impossibly difficult. But it takes meticulous, step-by-step planning and extreme caution. Know exactly what you want to accomplish before you start.
Of course, before you make such profound changes to the partition and/or file structure on either drive, back up your important programs and data.
