CANNOT CHANGE START MENU

Binary package hint: grub-pc

Hi

I'm on Ubuntu Lucid, version of April 4th

Actually, despite Ubuntu doc, I cannot change anything in the "start menu" line corresponding to Lucid start.

I wanted to have the "start menu" looking like this: Ubuntu 10.04 Lucid, Linux 2.6.32 ….
instead of: Ubuntu , Linux 2.6.32 …. (with no version #, what kind of Ubuntu is it, 9.10 - 10.04?)

So, as the doc says, in /etc/default/grub, I replaced
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
By
GRUB_DISTRIBUTOR=`echo -n $(lsb_release -cir 2> /dev/null || echo Debian)`
Then : sudo update-grub
And reboot

Big surprise: in the start menu the only thing remaining was "Windows Seven"!! a shame!

I've tried to investigate and did the following:
As previously, I changed the line in /etc/default/grub, but I did not replace "–i –s", I just added "-r" to it

That means that if you change anything behind the "-" argument, grub is lost and displays NOTHING regarding the current version.

I did the same thing in Karmic, but it worked. Hope you can fix this
