Well this place is my last stop and i quit if i cant find help here...
my problem is and this has been the same problem i have been having from Red Hat Linux 9 , Mandrake and now to Fedora Core 3...
i installed Fedora Core 3 after it was done i rebooted and it says "Operating System Not Found" i have tryed letting fedora set up the partiton for me and i have tryed to manully but none of the ways work for me im trying to install it on a ATA Hard Drive anyone here have a site or can telling me what i am doing wrong im sorry that i cant add more to my problem or give any more information due to me not knowing what all you need to know.. but this has been a problem like i said i have this same problem with red hat 9 and mandrake and now fedora core 3

Which bootloader are you using? Grub? Lilo?

Grub and it is the only bootloader i can see that i can pick for fedora core 3 but for the other 2 like red hat 9 and mandrake i tryed both types of bootloaders..

And how did you configure it?

i set it was defualt didn't change anything... however i have not been able to use mandrake or fedora yet i was able to install red hat linux 9 and it is fine till i restart my system then something happens to the bootloader and the only thing i can do is use the bootdisk to get back to the desktop.....

For the love of god someone help me get this problem fixed.... why does it have to be so hard for new people to understand?

It sounds like a Grub/hardware issue. I have one system that will almost never boot after a fresh linux install, but fixing the grub setup fixes the booting problem.

Here’s something to try. Boot into the rescue mode of whatever linux is installed on the system, usually by booting from the 1st CD and entering “linux rescue” at the prompt. You will be asked several questions, the last of which will be about searching for linux installations. After the search, you will get a prompt. Issue the command:

chroot /mnt/sysimage

Now run:

grub-install hd0

or

grub-install /dev/hda

This is covered in the Grub Manual ( http://www.gnu.org/software/grub/manual/grub.html ) under “Installing GRUB using grub-install”.

I personally have mixed success using grub-install in linux rescue mode, so if it fails, follow the grub manual instructions under “Installing GRUB natively” by using the grub “find...”, “root...” and “setup (hd0)” commands.

Another way to do a “native” grub install is to make/use a Grub Boot Floppy as is described in the grub manual under “Creating a GRUB boot floppy”. This is how I usually fix grub problems, since you can quickly boot from the floppy and fix the grub problem. Unfortunately, making the floppy with a dead installation is usually difficult for newcomers.

Another option is to get a live-CD linux like Knoppix ( http://www.knopper.net/knoppix/index-en.html ) and to do the grub repair after booting the live-CD. It’s really nice to have a live-CD linux for doing repairs when the system will not boot.
