Create Bootable Windows ISO Image from Extracted Files

It happened to me one day while helping my friend install Windows 8. We were working on Windows 7 and he gave me the download link and CD key to create a bootable drive. I’m not sure what went wrong, but for some reason, the USB couldn’t be created as a bootable device.

The USB still had all the necessary files to install Windows, but it wasn’t booting. It was now up to me to figure out how to make a bootable USB or DVD from these files. Otherwise, my “tech support” visit to his house would have been in vain.

All I needed was freeware to create a bootable ISO from these files.

After researching, ImgBurn was the program that helped with the task. Let’s see how the tool can be used to create bootable Windows ISOs from files.

Step 1: Download and install ImgBurn on the computer with the installation files. The tool comes with bloatware, so make sure to uncheck the corresponding option during installation. Once installed, launch it. In the app’s module selector, choose the option Create image file from files/folders.

Step 4: Click Build and wait for the tool to process the ISO file. Once the ISO file is created, you can burn it to a DVD or USB Drive.

Cool Tip: You can include freeware installation files or PC drivers on the bootable disc. This eliminates the need for separate sources for your Windows 8 installation and post-installation files.

Using ImgBurn, you can create bootable Windows ISO files from only the installation files/folders. The process is simple, but if you have any doubts, ask in the comments section.
