Boot Drive refers to the storage device from which a computer or device loads its operating system during the boot process. It contains the necessary files, such as the operating system and boot loader, required for the system to start and operate. The boot drive can be a hard disk drive (HDD), solid-state drive (SSD), USB flash drive, CD/DVD, or any other storage medium configured to hold bootable software.
The primary boot drive is typically the main storage device where the operating system is installed. In most systems, it is designated as the “C:” drive in Windows or the primary volume in macOS.
A boot drive can also refer to a USB drive or disk used for system recovery or installation purposes. These drives contain the files needed to install or repair an operating system.
