SOLVED: Installation adds GRUB on the second pass?

[pccobbler]

I installed Sparky Xfce. I was surprised to see a dialog concerning Grub after installation was complete and booted into the new system. Is that the way Sparky works or did I miss a step? I've never seen a Grub option after installation was complete. And how do I select the proper partition? I tried the keys I had used before, but I could not figure out which key it wanted.

From time to time system upgrade will try to reconfigure stuff (like for example bootloader). Sometimes this action require user intervention. You move around dialog box with arrow keys, space bar marks your choice, enter confirms.
