The boot drive is the drive in a computer system that contains the operating system and is used to start up the computer. It is also known as the system drive. During startup, the computer's BIOS/UEFI program reads the boot sector of the boot drive, which contains the necessary information to load the operating system.
The boot drive can be a hard disk drive (HDD), a solid-state drive (SSD), or any other type of storage device that is capable of storing the operating system. In most cases, the operating system is installed on the boot drive during the initial setup of the computer.
If a user upgrades their computer by installing a new storage device, such as an NVMe SSD, they may need to set the NVMe as the boot drive in the system's BIOS/UEFI settings. This is necessary to ensure that the computer is able to start up properly using the new storage device as the source for the operating system.
