How to Create Windows OS ISO File on a Bootable USB Flash Drive

Create Windows OS ISO Bootable USB Flash Drive


Windows USB/ DVD Download Tool (WUDT)

Scenario: Most of the latest Windows OS ISO files are above 4.8GB file size. A single layer DVD can only hold up to 4.7GB. Thus, you are not able to burn the ISO file into DVD SL. Here's the workaround for it using USB flash drive.

Solution: 
1. Download and save ISO file to your local HDD.
2. Download and install "Windows USB/DVD Download Tool" from CodePlex.
3. Prepare and insert a USB flash drive, 8GB and above (Must be larger than your ISO file size).
4. Run "Windows USB/ DVD Download Tool".
5. Choose ISO source file.
6. Choose media type "USB Device".
7. Browse to the correct USB Device and click "Begin Copying".
8. Wait for bootable USB flash drive creation to complete (All existing date on USB flash drive will be erased. Entire copying process could take anywhere between 5 to 10 minutes).
9. Insert USB flash drive into PC that you want to reformat.
10. Make sure boot option in BIOS is set to USB as the first boot device priority.
11. Install Windows OS normally like using any DVD installer.
12. Unplug USB flash drive after Windows OS automatic reboot during installation (You may stuck in installation loop for certain BIOS).

Note:
1.You must have basic knowledge in BIOS to perform BIOS option settings.
2. "Microsoft .NET Framework 2.0 Service Pack 2" must be installed first before installing WUDT.
