I do what is in the links that you post , and I used Windows USB DVD Tool (WUDT) but the same error messge appear to me..
I want to format a disktop PC which now is not work and doesn't have a dvd room, so I want to use bootable flash
when I start the format process it works fine and after a few minutes it's stopped and appear an error message that there are some missed or corrupted files...
I tried using different ISO files for windows 7 but no change.
If you don't know how to browse to select an ISO, how are you selecting an ISO to load on the USB disk? Where did you get the ISO files you are trying to put on the disk?
What is the exact error, your post cut off since you tried to put the post in the title instead of the message body.
The USB drive actually boots, then starts the setup of Windows right? But it can't copy any files over?
Try using a different hard drive with the computer to install Windows on, it may be an issue with the hard drive and not the flash drive that it can't read files from or copy to.
