-Permission denied message. (/boot/grub/grub.conf)

[jbapt]

I was hoping someone can tell me how to change the read write permissions in Fedora 12. I'm trying to obtain /boot/grub/grub.conf, but I'm getting a permission denied message.

Welcome to the forums!

You should be able to go to a terminal and use the su command to gain root privileges:

su

...or

su -

...enter your root password when requested and press ENTER. Once done, you should be able to access files that require root privileges.

Ozar,
Thanks for the help. I was already login as the root. Please look below and offer any other suggestions. THX!


[jsyn@localhost ~]$ su
Password:
[root@localhost jsyn]# /boot/grub/grub.conf
bash: /boot/grub/grub.conf: Permission denied
[root@localhost jsyn]#

Try it with the su - option. Note that there is a space between the su and the dash.

It looks like you are trying to run grub.conf as a bash script (which it is not), what are you trying to do? if you want to view the contents use cat (you don't need to do that as root)

cat /boot/grub/grub.conf

If you need to edit the file use nano (you will need root rights for this)

nano /boot/grub/grub.conf

You can check if the file exists and its permissions using

ls /boot/grub -l

the -l has a small L rather than a one

Here's my original problem. I've created 3 partitions. The original partition had Unbutu 9.10. I installed Windows XP next. I installed Fedora 12 last, which is on my second partition. Fedora and XP boots up fine. Fedora boots up by default and when I select other as an option, XP boots up automatically. However, when I select the Unbuntu boot, I receive an, " Error 15: file not found message". I ran the cat /boot/grub/grub.conf. Hopefully, I've provided enough info to get some help. I need to edit the my grub file it appears. Please advise.

Login as root and post the output of command,

fdisk -l

from your grub file

title Ubuntu (2.6.31-14-generic)
root (hd0,0)
kernel /vmlinuz-2.6.31-14-generic ro root=/dev/sda1 rhgb quiet
initrd /initrd.img-2.6.31-14-generic

try and mount /dev/sda1 and see whether ubuntu partition files still there or you have installed windows in /dev/sda1

as root,use mount command,

mount /dev/sda1 /mnt

ls /mnt

did you see ubuntu files?

Extract from grub.conf indicate you put Fedora on sda2 (hd0,1), Windows on sda3 (hd0,2), and Ubuntu on sda1 (hd0,0).
First lets confirm the partition structure, post the output of

su
fdisk -l

the -l has a small L not a one ...

also post the output of

mount
