What Is Boot X Drive?

Boot X drive is a term used to describe the process of starting up a computer using an external drive. This type of drive is typically connected through a USB port and contains its own operating system, allowing a user to bypass their computer’s internal hard drive and boot directly from the external drive. This process provides users with a simple and convenient way to test new operating systems, recover lost files, or run diagnostic tests.

The term “boot X drive” is derived from the fact that you are “booting” your computer using an external “X” drive, which can come in the form of a USB flash drive or an external hard drive. This technique is especially popular among IT professionals who deal with multiple operating systems on a regular basis, as it allows them to easily switch between different operating systems without having to modify their computer’s internal hard drive. Additionally, booting from an external drive can be a useful tool for troubleshooting system issues or recovering data in the event of a hard drive failure.
