I installed Fedora 14 first, then Ubuntu 10.04. I installed them using dm_crypt/aes256/lvm, so I used encrypted VolumeGroups. At the end of the Ubuntu install it said it cannot install GRUB, so I had to use SuperGRUBdisk to start Fedora and give the command:

# grub-install /dev/sda 

Now I can boot to Fedora normally, without using supergrubdisk, but the problem is, I can't boot to Ubuntu!

Is there any working way to install Fedora 14 & Ubuntu 10.04 using (separated) encrypted VolumeGroups (each volumegroup with other password)? Such that 2 users (who knows the root passwords of their own distro) can use 1 PC but not see each other's files?

Update: I tried it in reverse order: I first installed the Ubuntu, then the Fedora. Fedora didn't gave error messages regarding grub when installing, but it's still the same: I can't see the Ubuntu in the "grub boot list", when booting the PC.

What could be the problem? The boot manager doesn't recongize that, that there is another distro on the HDD? Why? What should i do?

Update#2: Here is my idea on a picture :) (on other pict. host)
