Klaus, at grub rescue type the following to get to normal grub>

grub rescue> set prefix=(hdX,Y)/boot/grub
grub rescue> insmod (hdX,Y)/boot/grub/normal.mod
rescue:grub> normal

note (hdX,Y) is where your ubuntu partition is, if you don't know, type 
this first
grub rescue> ls /boot
and the output will give you an idea.

After you get the normal grub prompt ie., grub>
type
grub> set root=(hdX,Y)
grub> configfile /boot/grub/grub.cfg

You will then be presented with the grub menu of the ubuntu that you 
installed. Boot into ubuntu and at terminal, type this...
sudo grub-install /dev/sda

You should be able to boot into windows and ubuntu then.


However.....if you cannot boot even to ubuntu by above method,.....
you may have a blotched ubuntu installation and you can still get back 
your windows by the usual method of using the windows installation cd 
the method of which I am not too clear, either fixmbr or fixboot
