A modern PC is configured to attempt to boot from various devices in a certain order. If a computer is not booting from the device desired, such as the floppy drive, the user may have to enter the BIOS Setup function by pressing a special key when the computer is first turned on (such as Delete, F1, F2, F10 or F12), and then changing the boot order.

When Secure Boot is enabled, it is initially placed in "setup" mode, which allows a public key known as the "platform key" (PK) to be written to the firmware. Once the key is written, Secure Boot enters "User" mode, where only UEFI drivers and OS boot loaders signed with the platform key can be loaded by the firmware.
The boot loader is responsible for accessing the file system on the boot drive, starting ntoskrnl.exe, and loading boot-time device drivers into memory. Once all the boot and system drivers have been loaded, the kernel starts the session manager (smss.exe), which begins the login process.

The boot partition is a primary partition that contains the boot loader, a piece of software responsible for booting the operating system.

In an OS/2 dual-boot configuration, the C drive can contain both DOS and OS/2. The user issues the BOOT command [1] from the DOS or OS/2 command line to do the necessary copy, move and rename operations and then reboot to the specified system on C:. Other systems provide similar mechanisms for alternate systems on the same logical drive.
