Bonus Tip: How to Create a Portable USB Drive?

A portable USB drive is different from a bootable USB drive. Creating a bootable USB drive requires you to download a Windows ISO file, and the size of the USB drive should be at least 8GB. However, creating a portable USB drive requires you to have a well-setted Windows computer, and the size of the USB drive depends on the used space of the 'source' computer's system drive.

With a portable USB drive, you can take your own system and files anywhere you want. And it won't be limited by the model and brand of computer. You can use your portable Windows 11 USB drive on an unsupported PC, or you can use it on a Mac computer.
