Well done.
Looks like you have successfully installed HS onto your SSD.
Next step is to enable that SSD to boot WITHOUT the USB stick.
To do that, you have install Clover onto the SSD.
I always use the original Clover releases from the developers.
But you can use the one on this site
here.
The options do not matter too much as you are going to replace the core of it with what's on your USB.
Installing Clover does two things. 1 it installs a 1st stage boot loader on your SSD that allows the BIOS to boot Clover. 2. It installs the Clover files in the EFI Folder (which we do not care about as we are going to overwrite them with what's on your USB).
Once it's installed, MOUNT the EFI Partition on the USB using
EFI Mounter.
Copy the EFI Folder from the USB EFI Partition to your Desktop (using Finder drag n drop).
UNMOUNT the USB EFI Partition.
MOUNT the SSD EFI Partition.
Delete the EFI folder at the root of your SSD EFI partition.
Copy the EFI Folder on your desktop to the root of your SSD EFI partition.
Restart your system and boot from your SSD.
