Update: revised step 4 to make it clear the path depends on where your WinSetupFromUSB folder is located and also noticed the WinSetupFromUSB author's website has a redirect issue. Alternative download link found here.

Issue

WinSetupFromUSB is great utility for creating a "multiboot" usb stick, great for technicians who want to only carry around less USB sticks while still having all the different installation media available. On my 64GB USB3.0 stick, I've got Windows 7, 10, DBAN (secure erase), Clonezilla (disk cloning), Hiren's BootCD (troubleshooting) and a variety of linux distros.

Recently, when adding any versions of Windows Setup ISO image file to WinSetupFromUSB the following error occurred -

Error!
This doesn’t seem to be valid source!

Either or all of \sources\boot.wim, \bootmgr

\boot\, \boot\BCD are missing, or source is not supported.

RETRY to select another source or CANCEL to return to the main menu
Retry | Cancel

Solution

To resolve this error the “WinSetupFromUSB-1-8\files\tools” folder path needs to be added to ‘Path’ environment variable.

  1. Windows Start Menu > Settings > find "View advanced system settings
    Shortcut: Open Start menu then type "advanced system".
  2. Go to Environment Variables
  3. Select User variable "Path" then Edit...
  4. Insert New and put in the full path to <...WinSetupFromUSB-1-10\files\tools>
     path depends on where your WinSetupFromUSB-1-* is located
    e.g. for me it's:
     "C:\Users\itsol\Downloads\WinSetupFromUSB-1-10\files\tools"

    Hey Rob,

    Windows is not case sensitive but I can see a potential issue with step 4 that I will make more clear: that you need to use the folder path depending on where WinSetupFromUSB-1-* is located.

    For instance I just downloaded it the latest version, and my path is: C:\Users\itsol\Downloads\WinSetupFromUSB-1-10\files\tools

    Did that solve it?

    And it has to be set to the tools folder? Is there some kind of exe to point to? Also, I for sure have tried it pointed to the tools folder and to the exe in the root of the folder. Neither have worked. Lastly where did you download their latest version, the website is down here in the states. I was messing around with some environment variables with another program and im afraid I may have deleted something important in the variables.

    Can you take a screenshot for me so I can see what else are in your variables? Not sure if there is sensitive info on there but I think I'm either doing something wrong or maybe I deleted something in there I shouldn't have
