USB boot

USB Boot is a method of booting or starting a computer from a USB device, commonly a flash drive. The main advantage of USB booting is that it is a fast and efficient way to start up your computer without needing to use a CD/DVD drive or an external hard drive. It is also beneficial for those who don’t have an optical drive or don’t have enough space for an external hard drive.

The USB boot technology was first introduced with the USB 1.1 specification in 1998. Since then, various external hard drive manufacturers have developed their own proprietary ways for enabling the USB boot feature. Originally, USB booting was used only for read-only purposes, such as booting from a rescue disc. Nowadays, USB booting can be used to boot from a variety of operating systems, such as Windows, Mac OS, and Linux.

In order to use USB booting, a USB device must be prepared by formatting its drive with the FAT32 filesystem before being plugged into the USB port. The boot device should also have an operating system installed. Upon powering on the computer, the USB device should be detected by the computer’s motherboard, and the user must then select this device as the boot device in the BIOS settings. After this, the operating system will be loaded from the USB device.

USB booting is a useful tool for users of all levels who wish to start their computer quickly or boot from an external drive. It is also a great method for troubleshooting, as many operating systems can be booted from USB.
