Dato che la mia sfera di cristallo mi dice che stai usando Ubuntu, prova con
$ sudo update-grub

Fatto. Apparentemente ricostruisce la lista ma riavviando non cambia un tubo.

Sei sicuro di averlo installato bene sto kernel? è molto difficile che 
update-grub (che viene richiamato ogni volta che installi un pacchetto 
kernel tra l'altro) sbagli.

Sempre assumendo che tu abbia Ubuntu prova a fare un
$sudo apt-get install --reinstall linux-image-XXXX (dove per XXXX intendo
la versione del tuo kernel

Ho Ubuntu 9.10.
Ho installato StartUp-Manager, l'ho disinstallato ma il problema non è
cambiato. In effetti sembrerebbe essere installato il kernel .20.

 Allego il mio menu.lst
Ok, allora il menu.lst e quello che vai a modificare con StartUp-Manager è
GrUB "1", in realtà la schermata di avvio che hai postato è di grub2. Nel
menu.lst c'è il kernel e relativa indicazione ma non è stata portata su
grub2. prova a usare: 
$ sudo update-grub2 (ricorda il 2)
Per passare ad utilizzare soltanto grub2 in Debian c'è il comando:
# upgrade-from-grub-legacy
che credo ci sia pure in ubuntu, anche se ubuntu 9.10 dovrebbe già montare
grub2. Comunque, *in caso* dai il comando:
$ sudo upgrade-from-grub-legacy
per utilizzare grub2 stabilmente.
Curiosità: ma hai fatto un upgrade o installato la 9.10 da zero?
