@Nurse_2014,
Welcome to the HP Support Community!
I reviewed your post and I understand that want to know whether you can move the operating system onto an SD card.
Don’t worry, I assure you I will try my best to get this sorted.
I would like to inform you that you will not be able to move the operating system onto an SD card. However, you can free up space on the following steps in the below article.

Let me know how it goes and you have a great day!
If you wish to show appreciation for my efforts, mark my post as Accept as Solution. Your feedback counts!
Cheers!
