Admin name on mac High Sierra

I recently posted article asking how to change the administrators name. However ,I just discovered that there is no administrator listed and I would like to put my name as an administrator. I recently bought this laptop and never knew that it would be so difficult to add my name. I am planning to change the HDD to SSD but i'm wondering if I could put my name in as administrator before cloning the Drive.

Thanks for your attention.

Depends on a few factors, but...

See if you can create a new administrator account by restarting the Setup Assistant:

Boot into Single User Mode: Start/restart your Mac. As soon as you hear the startup tone, press and hold ⌘ + S until you see a black screen with white lettering. (If you end up back on the login screen after a flash of the black screen with white lettering, enter your password and it will return to the black screen.)
Check and repair the drive by typing /sbin/fsck -fy then ↩ enter - as directed by the on-screen text.
Mount the drive as read-write by typing /sbin/mount -uw / then ↩ enter.
Remove the Apple Setup Done file by typing rm /var/db/.AppleSetupDone then ↩ enter.
Reboot by typing reboot then ↩ enter.
Complete the setup process, creating a new admin account.

Be very careful to notice the spaces in those Terminal Commands.

Once you've done that the computer reboots and it's like the first time you used the machine, except all your data will still be there. Your old accounts are all safe. From there you just change all other account passwords in the account preferences!!
