Hello,
This might work for you. If you know where your data is, and hopefully, you made partitions besides the / partition, you should be able to isolate the data, and re-install Fedora 3. Then, edit /etc/fstab to bring your data partitions back online.
For example, here is my partition layout:
[christian@frodo ~]$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda1 497829 269544 202583 58% /
none 257808 0 257808 0% /dev/shm
/dev/hda5 3020140 254392 2612332 9% /home
/dev/hda3 4032124 1334764 2492532 35% /store
/dev/hda6 1510032 35468 1397856 3% /tmp
/dev/hda2 8870804 4104600 4315584 49% /usr
/dev/hda7 1004024 147588 805432 16% /var
/dev/hdc 8285408 8285408 0 100% /media/cdrom
In my case, I could re-install, just as long as I leave /home alone.
I am not aware of any ways to install lilo unless you are in the environment.
I am curious, if you were using your HDD for booting the system, why you had a floppy disk involved.
