OK, it' looks like a standard default Fedora installation.

The Knoppix desktop shows hda1 and hda2 but in my experience does not
mount them. It just recognizes that they are present. But your
Knoppix might be different from mine.
If Knoppix has mounted hda1, you should be able to make it writeable
by right-clicking on its icon and selecting something like "make
writeable". That's the purpose of the "rw" in the command line,
stands for "read and write". On the command line, to make an
already-mounted disk writeable:
# mount -o remount,dev,rw /mnt/hda1

This shows that Fedora has hidden grub-install from you, it must be
somewhere in the LVM on hda2.

So you have to use the grub-install that resides on the Knoppix disk.
# grub-install --root-directory=/mnt/hda1 /dev/hda

There will be no dual-boot option, since grub-install will not find
any Windows to make part of a dual-boot system.
This is the second approximation. Again, if this works you are done,
if it doesn't work, give the details of what happened and we can try
for the third approximation.

It worked partly. I got to grub install part and entered:
# grub-install --root-directory=/mnt/hda1 /dev/hda
The result was:
This is the contents of the device map /mnt/hda1/boot/grub/device.map
(fd0) /dev/fd0
(hd0) /dev/hda
I then shutdown, removed Knoppix CD and rebooted.
It was able to boot from the HD, but it only got to the prompt
grub>
What should I enter at this prompt?
