Recently, I want to create a boot-able USB to re-install windows 7. And after creating boot-able USB with Windows7-USB-DVD-Download-Tool and windows7.iso, I can't boot from my usb. However, If I try to create with my friend's USB, I can boot from it (tried it many times)! So can anyone explain what 's happen to my USB? How to solve it? One more problem, when I stick my USB to my laptop, there's always a file named "usb label name".exe in my usb (if I try to remove it or even format it, it will be automatically created later)? Can anyone give me a way to remove it? Thanks in advance for any help you are able to provide!
