i have windows 7 installed (i install it first because for me it was always easier to have dual boot working) and i want to install 12.04 (i've tried 11.10 and 11.04 and i have the same problem) but i can't make dual boot works.
When i install w7, the installer create an additional partition with the loader (i'm not sure what is in this partition because other installers didn't create it) so in sda1 is a small partition with the loader and in sda2 is the windows 7 partition.
when i try to install Ubuntu, i create a partition for the / directory, one for the /home and one for swap. After install Ubuntu grub never starts and w7 starts automatically.
i tried setting the sda1 (while i am installing Ubuntu) as the boot directory but grub didnt recognize w7 (and i couldn't add it to grub). After reinstall w7 and Ubuntu i tryg the clasic 'fix' for grub the windows 7 loader keeps but showing a message that it is broken (and that i must use the w7 disk to restore it).
i hope someone has a solution for this, i search a lot but i can't found a solution.
