Lezárt Windows 7 USB Installation does not load drives!!!!

    Hi all,

    I have created an bootable USB drive to install Windows 7 ultimate from it. I have successfully loaded the machine from USB drive and everything went fine. That is windows copied the files, set up started, selected language. At the point where we have to select the drive to install the OS it shows me an error message. The message is as follows.

    "A required CD/DVD device driver is missing. If you have a driver floppy disk, CD, DVD or USB flash drive, please insert now"

    "Note: If the windows installation media is in the CD/DVD drive you can safely remove it for this step."

    It has an option to browse for the files and an OK button. The drives that we normally see when the windows is loaded is not at all shown on this screen. I have tried to load it on another machine also and the same problem is there also. Please help me to find an  answer.

     

    Thanks in advance:

    Jay

      I found the solution!!!!!

      The normal Windows 7 MCTS exam text says to create a bootable USB as follows.

      1. diskpart
      2. type "list disk" and you will see all connected disks and numbers
      3. select disk X (X being the number of the usb disk )
      4. clean
      5. create partition primary
      6. format fs=fat32
      7. active
      8. exit 

      But what i found from another link is to select primary partition before you format it, and also to assign drive letter for it.

      So the correct steps will be as follows.

      1. diskpart
      2. type "list disk" and you will see all connected disks and numbers
      3. select disk X (X being the number of the usb disk )
      4. clean
      5. create partition primary
      6. select partition 1
      7. active
      8. format fs=fat32
      9. assign
      10. exit

      Now copy and paste the files and folders from windows 7 DVD on to the USb and boot the machine from the USB drive.

      Another work around what I did (Not sure whether that had any role in the solution or not) was to make the USB as optimize for performance.

      Thanks Jay
