So the question was: How to change the order of the options and the default option of the Ubuntu grub loader?
And the answer is the following:
1. Enter the O.S Linux Ubuntu
2. Open the terminal
3. write the following command: "gksudo gedit /boot/grub/menu.lst" (don't forget "gksudo"!)
This command will open a kind of notepad with the file "menu.lst" which describes all the configuration settings of the grub loader menu =)
4. Find the blocks of lines corresponding to the various menu options and order them the way you want them. Be careful not the delete any code you shouldn't delete =)
5. Furthermore, if you want Windows to be the default option, find "default number", and change the number from '0' to the number of the option corresponding to Windows.
6. Save it all and try it!
I hope I helped a little =)
