The last version of Ubuntu to include legacy GRUB was 9.04 Jaunty.

Not quite sure what to do with GRUB 2. Just started using the newer
Ubuntu's. Haven't upgraded since Jaunty and am still learning GRUB 2.

DV6700z. All touch sensitive buttons work except for DVD and
QuickPlay. Related, all buttons on the included remote control are
functioning with the exception of DVD, QuickPlay, and Windows Logo
(Super key). Nothing I tried
