Installing All Versions of Windows 7 From USB Flash Drive Using ISO file

In preliminary experiments I've failed over 3 days. What's going on every time the installation was this error message appears "A required CD / DVD drive device driver is missing. Please insert the installation media ... etc ...". What a duck!!

Several of the legal ISO file were downloaded from the web 'https://sites.google.com/site/linuxlablibrary/windows-iso' using Download Accelerator to accelerate download more than 3GB in size of each file! After that I check the MD5 checksum by using software called "md5 checksum calculator"(there are many others software with same function, just Google). Unfortunately, none of the same with the MD5 checksum listed on the web https://sites.google.com/site/linuxlablibrary/windows-iso '.

On the fourth day, before I decided to send it to your nearest computer store, I tried for the last time by downloading the usual way without using any Download Accelerator. After finished downloading, I check the MD5 checksum by using software named "md5 checksum calculator" and then as usual, I kept comparing the MD5 checksum with the one shown on the website 'https://sites.google.com/site/linuxlablibrary/windows- iso '. Then.... Yahooo !! both are the SAME!

Now, this screen appears instead of screen "A required CD / DVD drive device driver is missing. Please insert the installation media ... etc ...".

The moral of the story is, DO NOT USE ANY DOWNLOAD ACCELERATOR TO DOWNLOAD THE ISO FILE!

**Tips for moving Windows 7 ISO file to USB Flash Drive:

1. Plug your USB Flash Drive into your PC.
2. Use the software called Rufus (please Google to get the latest version).
3. Leave it in its default state and enter the ISO file with the click of a button like a circle below.
4. Click the START button to start the process (this will take some time depending on the performance of your PC. Probably almost an hour).

Good Luck!
