- Boot from floppy, load CD drivers, copy CD content to hard disk and run setup from there
- If that is not possible (for example, hard disk too small): Boot from floppy, load CD drivers, run setup from CD, and immediately after the first reboot, boot from floppy again and manually copy the CD drivers from floppy to C:\autoexec.bat and C:\config.sys so the Windows setup can use the DOS drivers.
