Modify Boot Loader (GRUB) in Ubuntu 10.04

If in our computer have more than one OS (Operating System), for example the Ubuntu and Windows, and we install Windows first and then Ubuntu, then we have the Boot Loader (GRUB) provided by Ubuntu.

How do I modify the Boot Loader (GRUB) on this Ubuntu?

Here's a little that I can share:

• Open a terminal and type sudo gedit /etc/default/grub
  Will open the grub file. We can change its time-out and default (Default OS run, Windows or Ubuntu). If we only have 2 Operating Systems, Windows and Ubuntu 10.04 for example, then change the default from 0 to 4, then if we turn on the computer and do not select, so Windows will be run.
• Do not forget to press the Save and Close
• Then type sudo update-grub
• The next command sudo gedit /boot/grub/grub.cfg
  Grub.cfg file will appear. Here can be replaced string that is displayed in the GRUB. Suppose we want to replace the words "Windows XP" to "Door XP" or "Neighbor Door" hehehe .... :D
  
• Click the Save button (Ctrl-S), Close and Restart Computer, or can also be typed sudo reboot

Thus that can be shared by John Salim, hopefully useful...
