Edit your /boot/grub/grub.conf (or /boot/grub/menu.lst) so that the entry that looks like

title Windows 7
    ....
    ....

is the topmost of the entries (they all start with title)

You need to either log in as root (su) or use sudo, e.g. sudo <your favourite editor> /etc/boot/menu.lst

@IndianGirl I would try to edit the file like this on ubuntu/debian: sudo vi /boot/grub/grub.conf. Maybe your problem with editing is more complex than that, i don't know. –  Ben7005 Aug 9 '12 at 19:07

Thanks to Kimvais for the location of the file, that was most of the answer!

To start, type in sudo vi /boot/grub/grub.conf.

This command works like this:

  • sudo tells Centos that you want to perform the rest of the command with root privileges (so that you can save the file).
  • vi /boot/grub/grub.conf tells Centos to use the vi program to edit /boot/grub/grub.conf.

Now that you are in vi, navigate (using arrow keys or h=left j=up k=down l=right) to the place that you want to edit and change the values that you want.

Now press Ctrl+C, then :wq, then hit Enter.

This works like so:

  • Ctrl+C sets vi to command mode
  • : begins the command
  • w means save
  • q means quit
  • Enter runs the command, saving your file and then exiting vi.
