How to Write ISO Files to a USB Flash Memory?
Writing ISO files to a USB drive is a common task, especially when installing an operating system or running specific software. ISO files typically contain complete system images or installation files, and by writing them to a USB drive, you can create a bootable device. Below is a simple step-by-step guide to help you through the process.
What You’ll Need
Before you begin, make sure you have the following:
1. A Computer: Any computer with USB ports and the ability to read/write to USB drives will work.
2. A USB Flash Drive: Use a drive with at least 8GB of storage to ensure it can accommodate the ISO file and any additional startup files. Note: The USB drive will be erased during this process, so back up any important data beforehand.
3. An ISO File: Choose the appropriate ISO file for your needs, such as an operating system installation file or a software installer.
