If you are cloning, then that means you must now have 2 partitions with 
Fedora 14. Since you cloned, it might not be easy to tell which system you 
are now running, the original or the clone.

You can only have one grub installed. Since you can boot "one time" then grub 
must already be installed. Otherwise, how do you manage to boot?

Reinstall grub, just to make sure it is in the right place. I find it best to 
have grub on the MBR of the *first hard drive* eg., on /dev/sda (not on 
/dev/sda1 or /dev/sdb or whatever).

To install grub, as root and from the command line (not from the grub shell, 
like the ubuntu formum says--that is another way, but doesn't always 'take'. 
I had a problem with that once, too). Boot into your *main* operating system 
and run:

grub-install /dev/sda

Then, boot into the main system and edit /boot/grub/grub.conf to add menu 
entries for the various partitions that have operating systems. Editing 
grub.conf on other systems will not change anything. It must be the grub.conf 
on the system you ran the grub-install command on.

If Windows or some other program overwrites the MBR, don't worry. Just 
reinstall grub from your main system:

grub-install /dev/sda

Not at all.

Not a clue. Hope this gets you further.
