Building a bootable USB drive seems challenging, with little direction, but you will be ready in no time. Without a DVD or another media, bootable USB devices let you install or troubleshoot an operating system.
Introduction
- Why You Need a Bootable USB Drive
Whether you need to install or repair an operating system (OS), a bootable USB drive can be quite useful. It starts your computer straight from the USB drive; therefore, it avoids the current OS.
- Bootable USB Drives Benefits:
USB drives are speedier, more durable, and simpler to carry about than DVDs. Additionally, they offer greater flexibility due to their simple upgradeability with the latest OS versions.
What You Need to Get Started
- A USB Flash Drive
You’ll need a USB drive with at least 8GB of storage (16GB or higher is ideal).
- A Compatible Operating System File (ISO)
The ISO file contains everything needed to install an OS. Most websites offer free downloads for popular operating systems.
- Reliable bootable USB software
To create a bootable USB, you’ll need software that can help you place the ISO file on it in a format that the computer can use to start up. Rufus, Balena Etcher, and Disk Utility are all popular picks.
Choosing the right USB drive
- Recommended Storage Capacity for Different OS
For Windows and most Linux distributions, an 8GB USB is enough. If you’re installing a large OS, like some advanced Linux versions, consider a 16GB drive.
- USB 2.0 vs. USB 3.0:
While USB 3.0 is quicker and can create and use the bootable disk faster, USB 2.0 performs well for most consumers.
Selecting the Right Software for Creating a Bootable USB Drive
- Rufus
Windows users prefer Rufus since it is quick and simple to use. It’s lightweight, and you may run it with either Legacy or UEFI boot modes.
- Balena Etcher
For Cross-Platform Balena Working on Linux, macOS, and Windows, it is well-known for its simple, intuitive UI.
- Disk Utility (for Mac)
Mac users can use Disk Utility, built into macOS, to format their USB drive, and then Terminal commands to make it bootable.
How to Download an Operating System File (ISO)
Locating Trustworthy Resources for Linux, Windows, and MacOS
Always download ISOs from reliable sources or official websites to prevent corrupted or dangerous downloads.
