Looks like Grub didn't install, if it can't find stage1 it won't boot. Also can't find the kernel (vmlinuz). Use Knoppix CD and check root and /boot partitions with 'ls -l' command to see if the files are there.

Did you check wires/cables?

I could find the files (/sbin/init and /boot/vmlinuz) through GUI in knoppix, so there are there.
sorry i dont know what stage1 one is and how im suppose to look for it.
I have checked the cables. i dont know if this is of any significance but the hard drive is a SATA

Boot from the CD\DVD

use "rescue installed system" it's the third entry down iirc.
Keep clicking yes or continue
When you finally get to a black screen with something like
sh# type in "chroot /mnt/sysimage" without the quotes, click enter.
Then type in "grub-install /dev/sda" without the quotes, click enter.

Now try rebooting without cd\dvd in drive.

Q? Did you install from an Fedora9 full DVD or a liveCD (there can be quirks)

To mmaybe work out any hd\fs errors If it's live Fedora CD\Knoppix boot from it.
Use the second button, and click unmount for you hard disk,
Then in a terminal\console "Applications > Terminal"
as root "su - root"
type in "blkid"
your are looking for something like "/dev/sda1: LABEL="/boot" UUID="NumbersandLetters" TYPE="ext3" "
/dev/sda2: LABEL="/home" UUID="NumbersandLetters" TYPE="ext3" SEC_TYPE="ext2 (if seperate home)"
/dev/mapper/VolGroup00-LogVol00: LABEL="Fedora-9-Live-i6" UUID="NumbersandLetters" TYPE="ext3"
type in "fsck /dev/sda1(2,3) whatver they are called, you may not be exactly the same.
The important ones bein /boot, /dev/mapper/VolGroup00-LogVol00, and /home if there.

When you have that info:
type in "fsck /dev/sda1 (/boot) Whatever you got for above blkid.
If it saye volume is mounted click NO-N
Otherwise clikc yes Y
Do the same command for /dev/mapper/VolGroup00-LogVol00, /home

ok guys i did the rescue system option from the DVD. All went ok.

chroot /mnt/sysimage
grub-install /dev/sda
was typed in and all seemed ok.
guys i really do think that the problem is NOT the BAD INSTALLATION of GRUB.
anyways any other ideas ppl?

Did the reboot go ok?

hi guys again
I put the hard drive on a different computer, and in that computer it booted just fine and the OS works on it and there is no problem, what so ever.

could this be a problem with the mother board of the original computer?
(before anyone asks, yes i have checked the BIOS setting of the original computer)

Maybe , or just a controller problem, cables ok?

the cables are just fine.
i have even replaced them just to make sure.
What is a controller and what can i do if there is something wrong with it?

The controller is the bit on the mb that controller the h\d.
If it's dead, just get an add in sata controller card, or attach h\d to another sata connector in the original pc if availabe,
but am guessing you already that.

You have not told is it single boot or dual boot.
Perhaps as installation went fine then there is no reason to get error .
When disk boot failure error comes , sometimes data-bus & power cord may get loosely connected.
Also you did not mention how you have made partitions,space allocation for each one of them.
It could give extra information .

If you have more than one HD make sure your BIOS is booting the correct drive. (Sometime one forgets the obvious things.)

Since you've confirmed that the drive boots properly in a different box, your problem is, clearly, related to the other hardware (not the HD) in the box you're trying to use. You've eliminated cables, so what's left is the mother board or the BIOS.

Suggestions:

1) Carefully review the BIOS settings in the subject box. pay careful attention to the HD support because some BIOSs default to an undocumented "Windows" drive support mode.

2) Check the box manufacturer site for BIOS upgrades, and install the latest one offered.

3) Replace the the mother board.
