recovering win7

[squareyes]

Hi, I have a laptop that I had win7 (came with it) and Ubuntu.
The monitor has been damaged but still works with an external monitor.

I have deleted partitions formatted them after deleting partitions and 
created a
single new partition, and used the recovery disks (5 dvd's), I elected 
to re-install everything,
thought that format the drive, but after re-starting I get a screen with

error:no such partition.
grub rescue>

The person who I am giving it too has to use Win7, I would prefer that 
she uses Linux but she won't.
Is there any command I can enter on
error:no such partition.
grub rescue>
to restore the mbr

Many thanks in advance, am not the most patient individual, have been 
close to tearing my hair out,
what there is of it.

Take care
Winton
