What is the term bootstrap in relation to computer booting process?

The term "bootstrap" in relation to the computer booting process refers to the initial sequence of operations that a computer performs when it is powered on or restarted. It involves loading the operating system into memory from a storage device, such as a hard drive or SSD. The term originates from the phrase "pulling oneself up by one's bootstraps," illustrating how the system initializes itself without external help. The process typically starts with the BiOS or UEFI firmware executing a series of checks and loading the bootloader, which then loads the operating system.
