​KembaraXtra-Computer Terms – boot disk:
A boot disk is a removable storage medium, traditionally a floppy disk, that contains the essential system files required to start a computer. It allows a computer to boot independently of the main hard drive.
Boot disks are commonly used when a system cannot start normally due to problems with the primary storage device. By inserting the boot disk into the designated drive, the computer can load the operating system and perform troubleshooting or recovery tasks.
