After installing the Sugar Learning Platform on my Windows 7 laptop, it now has GRUB bootloader with the following boot entries:
- Fedora 17
 - Advanced configuration
 - Microsoft Windows 7
 
And by default it goes to the first entry, which is Fedora.
Now that's a bit inconvenient, as I use Windows most of the time. Here's how to make the default boot switch to Windows 7:
- As su, grep menuentry /boot/grub2/grub.cfg to show the boot entries
 - vi /etc/default/grub By default, it'll say GRUB_DEFAULT=saved. If you run grub2-editenv list, it'll show you Fedora 17 as the default option.
 - grub2-set-default "Microsoft Windows 7" to change the default.
 - grub2-editenv list to confirm that the configuration change was committed.
 
Another option is to manually make the change:
- vi /etc/default/grub
 - GRUB_DEFAULT="Microsoft Windows 7"
 - grub2-mkconfig -o /boot/grub2/grub.cfg to save.
