[SOLVED] accessing another partition
I recently installed redhat beside ubuntu which in turn screwed up ubuntu's grub2 loader and now I can only start up rh. Could someone tell me how to navigate through the file system to Ubuntu's partition? If I click on > places, I see the icon, > 250 GP Hard Disk: 116 GB Filesystem. But once inside I don't have any idea where or if ubuntu's file system is reachable. Thanks.
One more thing, does anyone know why firefox on redhat does not spell check as I am typing as did firefox on ubuntu? Thanks again.

Ubuntu's partition should be accessible under Red Hat. Have you checked whether it's mounted?

This is a problem with RedHat and RedHat based distros. Installer doesn't detect other installed Linux distros. It's easy to add an entry of Ubuntu in RH Grub. We have to check partition structure of your Hard disk first.
Open Terminal and execute this
Post output here.Code:su - /sbin/fdisk -l df -h
Are you using same version of FireFox in both distros?One more thing, does anyone know why firefox on redhat does not spell check as I am typing as did firefox on ubuntu? Thanks again.It is amazing what you can accomplish if you do not care who gets the credit.

I did finally get access to the Ubuntu partition but I still need to get Ubuntu to load back up via grub or grub2, whatever the case needs be. Originally Posted by Garrett85

A lot of kernel versions have been installed in Ubuntu. Add latest version in GRUB Menu and if everything works fine, remove all other kernel versions using Synaptic.
Open /boot/grub/grub.conf file of RedHat and add this code at the end of file :
Save file and reboot machine.Code:title Ubuntu 10.10 root (hd0,4) kernel /boot/vmlinuz-2.6.32-29-generic ro root=/dev/sda5 initrd /boot/initrd.img-2.6.32-29-generic

I'M getting this error when I try to open the file from gnome "The file is of an unknown type", when I try to open it from the terminal as root, I get "permission denied" Thanks for working with me on this problem. Originally Posted by devils casper

You must have root privileges to edit grub.conf file and you can gain those privileges through su - command.
Code:su - nano /boot/grub/grub.conf
