Could you provide more information on your Fedora & Ubuntu installation. Do you have separate home directories (for your regular user).

Your question isn't clear to me on whether you mean that you can't access files in the Ubuntu install when running Fedora, or whether when you boot up Ubuntu, you can't access your own files.
How are the partitions mounted?
What is the UID of your user in each distro?
What is the the primary GID of your user in each distro?
What are the permissions of your home directories in each distro?

This should not give you any headache, Fedora can co-exist with Ubuntu and Xp peacefully. So long as you have installed Fedora in a separate partition everything should work alright. In this case, you did not even needed to install any boot loader for the latest fedora installation: you only need to add an entry into the /boot/grub/menu.lst pointing to fedora root, kernel, and initrd. Or is your Fedora using Grub2 ? That is another story. Get familiar with Grub bootloader, read from this page.

We need to know more about how you allocate your disk partitions, and apportion your different folders. Where did your install fedora? what does "fdisk -l" command return? post it here.

Hope it helps.

If you are now able to boot Fedora and have mounted and can read your Ubuntu files, just navigate to the Ubuntu /boot/grub/menu.lst file and copy the first entry for Ubuntu to your Fedora /boot/grub/menu.lst file. I don't use Fedora so the file may be grub.conf instead of menu.lst. I believe one is a link to the other. You need to do this as root.

You can solve this simply by editing " grub.conf or /boot/grub/menu.lst."

Actually i had also faced the similar situation.
* My university gives us a laptop loaded with Windows XP
* Then i had installed openSUSE ( becoz i like it, most of edu work can be done in SUSE )
* After that i had installed ubuntu. ( becoz it is simpler )

MY suse has the beatiful penguin theme to select different OS's. But when i had installed ubuntu , this bootloader removed. I hate ubuntu bootloader, it is looklike command mode prompt. So i had followed this.....

* After logging into the SUSE i had repaired the Bootloader , so that primary bootloader is SUSE.
* then SUSE penguin theme comes to select OS's.
* Now when I select Ubuntu, ubuntu menu displays , i had removed this by editing ubuntu "/boot/grub/menu.lst." Since i don't want to uninstall grub of ubuntu. May be it will be required for future purposes. So I had just made select time to 0.

SO Now " only penguin theme of openSUSE grub comes for me".

check for the file grub.conf.
It may be present in

/etc/grub.conf
/boot/grub/grub.conf

check for
title Ubuntu
rootnoverify ( sda??????????????)
chainloader +1


??? = your ubuntu boot partition.

If you are able to modify, make a backup and then try. or else post the code in that file.

Out of this my the root of my ubuntu was /dev/sda7. I mounted it onto my /media/disk-4 and collected the contents of ubuntu /media/disk-4/boot/grub/menu.lst, it is as follows:

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and

clearly saying, ubuntu is missing in your FEDORA grub.

Code:

[root@localhost grub]# cat menu.lst
# grub.conf generated by anaconda

In your fedora menu.lst make these modifications.

instead of

Code:
title other                               
rootnoverify (hd0,0)
chainloader +1
add this

Code:
title ubuntu
rootnoverify (hd0,6)
chainloader (hd0,6)+1

title other
rootnoverify (hd0,0)
chainloader (hd0,0)+1
I am not sure about this... make a backup... and then test it.

um...

you should just run
Code:
su update-grub
from your Fedora system

grub.conf is read-only and will be auto-edited
when using update-grub?

see if that works?
