When installing ubuntu 9.10 karmic koala will grub2 work together with grub legacy

[bqz69]

Then I tried to reinstall 9.10 on my laptop with following setup:

sda1 and sda2 9.10 encrypted

sda5 and sda6 8.10 encrypted

sda7 and sda8 9.10 encrypted

sdb1 and sdb2 8.04 encrypted

I reinstalled 9.10 encrypted on sda1 and sda2

It ended up with grub2 seing sda1 only

Then I edited from all the menu.lst and put those into 40_custom and ran "sudo 
update-grub"

I managed grub2 to see sda1, sda7 and sdb1 (I could not get it to show sda5, 
which I managed it to do during my first installation)

I also have to press shift button to get the grub2 bootloader showing, so I 
need to edit /etc/default/grub to fix that, but newbies will have problems with 
doing that, I predict.

So my overall impression, after twice having new installed 9.10 (which has 
grub2 as default bootloader) on two different computers, is that the grub2 OS-
prober system does not work properly during all circumstances.

I also tried the grub-mkrescue command to create a rescue disk, but when I 
boot the rescue cd, it only gives a "sh:grub>" prompt, i had expected it to 
give the whole boot loader menu, in the same way that SGD (Super Grub Disk) 
with grub legacy does.

When i boot with SGD I get sda5, sda7 and sdb1.
