1. Simply make a copy using UltraISO program, PowerISO, Daemon Tools ..... etc.,
2. You may download an ISO image from Microsoft websites.
Now, you made an ISO image from your W7 DVD, and you chose the first way (in my previous post) to make Bootable USB Drive and install Windows 7/Vista From this USB Drive.
But Oops! You got this ERROR Message in the 1st step when You hit NEXT
Now What's the solution? and What does this message mean?
Follow these exclusive steps:
1. Download "UltraISO PE v9.5.1 full version" from Mediafire
2. Make an ISO image from your W7 DVD. It's very easy (Insert your W7 DVD, Right click, UltraISO\Create CD/DVD image..., Choose iso extension, Done)
3. After you made an ISO image open it in UltraISO (Open with UltraISO, or double click). It'll open this window:
4. Hit the little right sign in the left pane. It will open this window:
Look at these settings *Joliet , *Omit ISO 9660 version number. Change these settings to the settings in the following picture (check UDF, Uncheck Joliet and Omit ISO 9660 version number) then HIT ok:
5. Save your previous Windows 7 ISO image (you are already opening it) as a new ISO image with these new settings look at the following pictures:
6. Now go back and open "Microsoft’s Official Windows 7 USB/DVD Download Tool". In step 1 browse to your new Windows 7 ISO image (UDF now not Joliet ):
7. Hit NEXT and congratulations You are in STEP 2
For PowerISO users, I received this tip:

I found an alternative way using another program, ImgBurn, that detected I wanted to burn an ISO file for Boot and install!! and made most of the settings automatically for me. After a second try, the W7 installed! Thanks anyway for the clues included in your tutorial, it helped me a lot. Rgds JG
I want to thank my friend Mahmoud Fikry (Godsmack) for his comments and feedback.
And I'd like to thank Abhishek for sharing my tutorial with others:
Please leave comments, I DID NOT USE GOOGLE OR OTHER TWEAKING WEBSITES. IT JUST TOOK 0.05 SECONDS OF THINKING TO GET THIS SOLUTION I CONVERTED THE DVD FILE SYSTEM FROM JOLIET TO UDF (I THOUGHT THE ORIGINAL ISO FROM MICROSOFT SHOULD BE UDF NOT JOLIET)
