Yeah, i didn't want to use the good'ol CDboot-and-chroot method to repair GRUB until someone more advanced than could maybe use the bug to eventually fix it. The repair worked fine, and i can merilly boot my 11.04 now. The command output you asked is attached to this message.
I may precise that my computer conf may have "tricked" in some ways the grub installer: sda: an old XP with only 1 partition sdb: an "automatic-use-the-whole-disk" ubuntu install Not so complicated actually, but what do you know...
