How can I install grub again and make it see all this Operating Systems?

Remove GRUB (sudo apt-get purge grub-pc) from all Ubuntu installations except one (I recommend 11.10 either 32/64 bit). This way, when one of your Ubuntu installations performs a kernel/grub update, it doesn't overlap with the grub configuration of the other.

Also, make sure that you have grub-pc version 1.99+ installed (apt-cache show grub-pc).

After you followed the steps above, run sudo update-grub to let GRUB detect all of your OSes.
