Best to do it from the terminal. Make sure you are logged in as root. The reason you get permission denied is you are doing it as a none root user. So when you open the terminal type su - then it will ask for the root password type that. Then you can use nano or gedit to edit the file.

Exact command will look like the following.

root%26gt; su -

Then enter root password



root%26gt; nano grub.conf

root%26gt; gedit grub.conf



if you do not have gedit installed just do the following command.....

root%26gt; yum install gedit.How to change default start from linux to windows xp?
in XP, try this ...

SYSTEM

ADVANCED

There you can see the start ups and select the default.
