If that happens,

remove the floppy disk from the floppy disk drive. On most computers, just push the
little button on the front of the drive and the disk will pop out (if a disk is in the floppy drive). Then press
any key on the keyboard (such as the spacebar, the Enter key, or some letter) to resume startup. Your
PC will then automatically go to your hard drive (drive C, as it’s called) and load the operating system
from that drive.
If you then see a prompt requesting a password, go ahead and type your password. Note that
passwords are case-sensitive. So if your company network administrator gave you a password, be sure
to type it using exactly the same upper- and lowercase letters provided. Be aware that whenever you
type a password, the letters you type won’t appear onscreen. Instead, you’ll just see a dot or asterisk for
each character you type. The purpose of the dots or asterisks is to prevent someone from peeking over
your shoulder to learn your password (technically known as shoulder surfing).
