So I've had my USB loaded with BT5 for a while now, one thing I've noticed is that I can't save, or make new files on it. Like for example, I'll make a random text document, save it to my root folder, when I restart and try to boot back into BT5 from my USB, it just loads windows. Is there something I'm doing wrong? Or am I just not supposed to have files saved on the LiveUSB that has BT5?
