Download the Windows 7 Bootable USB/DVD Download Tool by clicking here. Click and run the downloaded file, Windows7-USB-DVD-tool.exe. You will be asked to choose the ISO file for which you need to create the USB/DVD. Download the required Windows 7 ISO file (ensure that you have a genuine license or have purchased Windows 7).
At this stage, you should be on Step 1 of the Windows 7 Bootable USB/DVD Tool, along with the required ISO file downloaded. Click on the Browse button, select the downloaded ISO file, and click Next. Then, select your media type, either DVD or USB.
After you select the media type, you will be asked to select the appropriate device from the drop-down menu, as shown below. Select the correct media type and click on “Begin Copying.
You will see the progress bar as it writes to the media to create the bootable media. Once the process is completed, you will have successfully created the bootable media for Windows 7, which can be used to boot and install Windows 7 on systems.
Most devices now allow you to directly boot through USB; if this option is not available, then you can change the boot order from the BIOS. Look for options at start-up before the system brand’s logo is displayed.
These options are accessed by F keys; the most commonly used key to access BIOS is F11.
Note: This tool is also used for creating bootable media for Windows 8, 8.1, and 10. The procedure is the same.
