Windows disappear in grub/menu.lst after update of debian-lenny


Hi forum,
On my Toshiba laptop I have windows vista and debian lenny installed as dual boot. Last night gnome update-manager installed 32 new update. I did unfortunately not check what all updates were about and just clicked ok. Now a new grub menu.lst has been installed without windows vista. Starting gparted to see available disks I get the message:
Invalid mount option when attempting to mount the volume 'WinRE'.

What is going in on and how do I get back my windows boot-option?

Try reinstalling the grub. Do you have both operating systems on the same drive or you have dedicated drives for both? Where is grub installed by the way?

Where is grub installed by the way?

How to reinstall like "aptitude reinstall grub" ?

There is only one drive, - here is result from df:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda3 61116420 12460280 45551580 22% /
tmpfs 1553736 0 1553736 0% /lib/init/rw
udev 10240 108 10132 2% /dev
tmpfs 1553736 0 1553736 0% /dev/shm
/dev/sda2 156933116 98589152 58343964 63% /mnt/windows

grub is installed at /boot/grub

Here is my menu.lst - I have added a windows boot listing, but get the message "BOOTMGR" missing?

title Debian GNU/Linux, kernel 2.6.26-2-686
root (hd0,2)
kernel /boot/vmlinuz-2.6.26-2-686 root=/dev/sda3 ro
initrd /boot/initrd.img-2.6.26-2-686

title Debian GNU/Linux, kernel 2.6.26-2-686 (single-user mode)
root (hd0,2)
kernel /boot/vmlinuz-2.6.26-2-686 root=/dev/sda3 ro single
initrd /boot/initrd.img-2.6.26-2-686

### END DEBIAN AUTOMAGIC KERNELS LIST

# This entry automatically added by the Debian installer for a non-linux OS

Boot with debian cd into rescue mode and on command line just type:

grub-install /dev/sda

If you can boot into Debian then boot into and on terminal type

sudo grub-install /dev/sda
