In today’s world of portable computing, being able to take your operating system with you wherever you go is a highly desirable feature. One way to achieve this is by installing Linux on a USB drive. But can you fully install Linux on a USB drive, or are there limitations to this approach? In this article, we’ll explore the possibilities and challenges of running Linux from a USB drive.
What is a Live USB?
Before we dive into the world of fully installed Linux on a USB drive, let’s first talk about Live USBs. A Live USB is a USB drive that contains a bootable operating system, usually Linux, that can be run directly from the drive without the need for installation. Live USBs are great for trying out Linux without committing to a full installation, and they’re also useful for troubleshooting and repairing computers.
However, Live USBs have some limitations. They’re typically slower than a fully installed operating system, and they often lack the ability to save changes and settings. This is because Live USBs usually run from a compressed file system that’s loaded into RAM, rather than a full file system on the USB drive.
