Boot Disk or Boot Floppy
Normally, the floppy drive light comes on so the computer can tell if there is a boot disk in there. If there is a floppy in the drive that is not a boot disk the windows will stop loading until the floppy is removed.
The floppy disk has nothing to do with the operating system on the hard drive. You can use a floppy disk created in Windows XP to boot a computer that has Windows 2000, Windows 98, Windows 95, Windows 3.1, Windows Vista, Windows 7, Linux, Solaris, FreeBSD, etc...
After you make the floppy disc a boot drive (beforehand), you can use it to boot your system when you are unable to boot using your harddrive.

You need a boot disk to start it up. Either use your emergency repair disk that you created for that operating system. Boot up the machine and go into the BIOS and enable the "boot from floppy disk" or something similar. Put the boot disk in the floppy drive and reboot. Follow the instructions given; you need CDROM support enabled. When ready insert the W98 disk into your CD Drive and navigate to it's root directory (folder). There's a program called something like "setup.exe", run it and following the instructions. Otherwise, change the boot sequence to CD, IDE0, Floppy, and enable "boot from disk". Restart the machine, you'll be asked if you want to boot from CD. YES. With a new harddisk, you'll be asked to partition the drive. Which you need to do. Just accept the default, which is one primary DOS partition using the whole disk space. It will then format it to FAT32 file system. The actually windows 98 setup will then begin, follow the instructions on screen.
a Floppy Disk
No. A "system disk" is simply any disk which the computer can boot from and has an operating system installed on it. In most modern computer systems, the hard disk is normally the system disk. However most systems can also boot from a floppy disk, a cdrom, or even a USB thumb drive, providing of course that the media in question has the necessary system files on it. Many older systems did not have the ability to boot from the cdrom drive or USB drives. On these systems the only options were booting from the hard disk or floppy disk, so if the OS hadnt been installed to the hard disk yet (or it was broken) the only other option was the floppy disk.
