installed dual boot fedora and lost Kubuntu

[linux_mac]

i had Kubuntu 8.10 with KDE 4.0 interface and i decided to try out fedora to see if i liked it and wanted to eventually switch. i've done so many dual boot systems with Kubuntu and not had any problems that i decided not to back up my system this time before running the installation. after running the installation and shrinking my hard drive (200 gb) by 80 gigs, i rebooted to find that Kubuntu was no longer bootable. the first time i booted into fedora, disk utility popped up with a message that said "1 or more hard drives is failing". i ran the test that it recommended and found no problems. then i ran the longer test and still found no problems. i've rebooted a few times and have not been able to see Kubuntu in the boot loader options.
if you need any more information i will be happy to provide it. my question, obviously, is how can i retrieve my Kubuntu partition. it is still there but is not bootable. what do i do

this is the output of fdisk -l

So you're actually booting up to a functional Fedora install, right?
If so, what is the output of

cat /etc/grub.conf

[yancek]

If you don't see Kubuntu in the menul options of the bootloader I would assume you installed Fedora Grub to the master boot record. Fedora does not usually put entries in menu.lst file, you need to do that manually.

Check your menu.lst or grub.conf files as suggested above.

As yancek already mentioned, Fedora installer doesn't add entries of other installed Linux distros in its GRUB. You have to edit its grub.conf file manually.

* Boot up Fedora and mount root partition of Kubuntu.
* Open /boot/grub/menu.lst file of Kubuntu and copy first title block ( title, root, kernel and initrd lines ).
* Open /boot/grub/grub.conf file of Fedora and add Kubuntu's title block in it.

Save file and reboot machine.

the boot folder shows me nothing at all when i open it. this might be because i don't have the required permissions. how can i get them?

yeah, i was right. i just looked at the permissions in the properties and it says "you are not the owner, so you cannot change these permissions."

[jayd512]

What you'll need to do is mount the partition that has Kubuntu.
As root, do

cd /mnt
mkdir sdax                    replace the x with the appropriate number
mount /dev/sdax /mnt/sdax
cat /mnt/sdax/boot/grub/menu.lst

Then just copy the first title block into Fedora's menu.lst.

[linux_mac]

ok, i did the following steps:

cd /mnt
mkdir /sda6
mount /dev/sda6 mnt/sda6

that all went fine. i was, of course root but when i did

cd /mnt/dev/sda6/boot/grub/menu.lst
no such file or directory

so i tried going to boot and that went fine. but once there, ls shows me nothing int the file.
i don't think i have the permissions to view it.
