why I can not use the 3.2 kernel

[Chen Liang]

OK, after type this command, it displays:

slim at lab:~$ sudo update-grub
[sudo] password for slim:
Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst
Searching for splash image ... none found, skipping ...
Found kernel: /boot/vmlinuz-3.2.0-34-generic
Found kernel: /boot/vmlinuz-3.2.0-33-generic
Found kernel: /boot/vmlinuz-3.2.0-31-generic
Found kernel: /boot/vmlinuz-3.0.0-20-generic
Found kernel: /boot/memtest86+.bin
Updating /boot/grub/menu.lst ... done

And I see my /boot/grub/menu.lst file content is :

default 0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default
entry
# (normally the first entry defined).
timeout 3

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
hiddenmenu


## ## End Default Options ##

### END DEBIAN AUTOMAGIC KERNELS LIST

The 3.2 kernel titles do show in the menu.lst, but when I restart my
computer, I can't see the options. I really don't know why!
