The OS is installed on the HD, just like any other program. The bootstrap process loads the OS from HD to main memory, where it is executed.
How could a system be designed to allow a choice of operating system to boot from. what would the bootstrap program need to do?
On most computer systems, a small piece of code known as the bootstrap program or bootstrap loader locates the kernel loads it into main memory and startsits execution. Some computer systems, such as PCs, use a two-step process in which a simple bootstrap loader fetches a more complex boot program from disk, which in turn loads the kernel. The bootstrap program can perform a variety of tasks. Usually, one task is to run diagnostics to determine with the booting steps. It can also initialize all aspects of the system, from CPU registers to device controllers and the contents of main memory. Sooner or later, it starts the operating system.
How was the first os loaded onto the computer?
By first loading a small bootstrap program. The bootstrap program then loaded the OS.It is still done this way, except the bootstrap programon most modern computers is preloaded on ROM so it needs no special action on the part of the operator/user to load it as was needed on the early computers.Some early computers used a 2 stage bootstrap to simplify thing for the operator/user: the small bootstrap program loaded a larger more powerful bootstrap program, which then loaded the OS. This is not necessary with the bootstrap program in ROM, the large bootstrap program would be the one in ROM.
What memory stores bootstrap code?

The term booting up your computer is booting up is derived from?
The computer term bootstrap began as a metaphor in the 1950s. In computers, pressing a bootstrap button caused a hardwired program to read a bootstrap program from an input unit and then execute the bootstrap program which read more program instructions and became a self-sustaining process that proceeded without external help from manually entered instructions. As a computing term, bootstrap has been used since at least 1958 - now usually abbreviated to boot.
