Trying to make USB drive bootable in Windows 7

I bought a USB pen drive in order to make it bootable for Windows 7 Netbook.

The directions look easy
1. command prompt with admin privileges.
2. diskpart
3. list disk
4. select (usb disk #)
5. clean

when i try this i get message "media is write protected...." i do a little research and it try
ATTRIBUTES DISK CLEAR READONLY

I try that but still response "DiskPart has encountered an error: The media is write protected. See the System Event Log for more information.

Anyone know how to resolve this?

Thanks!

 

In addition, whatever I did has now made that pen drive unreadable in windows.

I was able to access drive before i tried cleaning it, now when i try to access it in windows i get message "please insert a disk"

I try to format it in windows and get message "windows is unable to complete the format"

 

1. Installing Windows 7 From USB Drive 3 Steps Easy Process
3 easy options for you to put the ISO image of your Windows 7 copy onto a USB stick, then install Windows 7 to your computer from your USB stick instead of burning a DVD and wasting a disc. Installing from a USB drive shaves a few minutes or so off the install time.

Note: Make sure your motherboard is capable of booting off a USB stick or this will not work. Also, backup any files on your USB stick because it will be formatted. Make sure your USB stick is big enough to fit the Windows 7 ISO image.





1st Option (Try This First)

Download Microsoft's official tool to install Windows 7 from your USB stick, the tool was removed from Microsoft's website for a short time because evidently the tool violated the GNU’s General Public License (GPL) for using open source code, but Cnet has the file hosted. Link below:

The tool can now be downloaded again from the MS Store:

2nd Option - Use Unetbootin

Follow the guide in the link below to use Unetbootin to Install Windows 7 from your USB drive, Unetbootin doesn't install anything to your computer unlike UltraISO, so I would use unetbootin if the 1st option above does not work for you.

3rd Option - Use UltraISO


1) Download the free UltraISO trial by clicking on this
2) Start UltraISO as administrator
3) "Burn" the iso image to the USB stick by following these steps

With UltraISO:
- Open the image of Vista/Win7 with UltraISO
- Under BOOTABLE tab choose WRITE DISK IMAGE
- Choose your USB stick under "Disk Drive"
- Choose a method (It's recommended to use USB-HDD+)
- Press Write
- Make sure to change your BOOT order in BIOS to boot from your USB drive first

 

"I bought a USB pen drive...."

If it was a cheap unbranded one don't waste your time get a Sony, Kingston, Sandisk or PQI stick
They cost a little more but it's worth it. If you get one off ebay do some reading into 'fake USB flash drives'
I have a lot of flash drives and the ones mentioned above have never given me any problems but cheap
unbranded ones have.
