Hey, welcome to Linux.org! :3 As the others have said, GParted will be key here.

But you should know that running any OS via USB, even on a regular Drive attached to a USB cable, is noticeably slower, and more prone to being unplugged (which could damage your Data, or worse, maybe the Drive itself).

Do you have a standard SATA HDD/SSD or NVMe SSD?

That would be a better approach.

But your way would certainly work, if you wanted to.
