First, pardon my english. First time posting about anything. I just installed ubuntu 12.04 in a partition of my hdd that already had windows 7. Seems like the windows loader (mbr?) is being read first and I don't even get to the grub menu. I guess that's happening because I chose to set the mountpoint of ubuntu on sda6 and the windows loader is on sda1. So how can I move the grub or the windows loader to make grub loader being read first upon booting?
