[kubuntu] Grub2 not working but Grub Legacy does

view story

http://ubuntuforums.org – Hi, I just finished installing Kubuntu 12.10 on a pc with windows7, using EasyBCD I was trying to add the boot entry to mbr. For some reason Grub2 did not work and when I chose Linux in the OS selection screen on boot, I would end up on the Grub4DOS screen instead of the usual Grub screen where you select a distro. I had to use Grub Legacy and point to the device. I have 2 questions: 1 - Why didn't Grub2 work? Since I started dual booting, I've only used Grub2 and it's always worked but why not in this case? 2 - If I want to add another distro would there be a complication if I used Grub (Hardware)
