GRUB not showing a menu

ETC Boot Loaders
1

Hi there,
I had a double boot of Windows 7 and Ubuntu 10.04. After messing up with UBUNTU I reinstalled it. But then Grub did not noticed the existence of my windows and it just boot into linux. I booted with windows 7 installation CD which noticed a problem with my booting and suggest to repair it and restart the computer. But it took sometime before restarting into UBUNTU. My partition table is

Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      102398+   6  FAT16
Partition 1 does not end on cylinder boundary.
/dev/sda2              13        1288    10240000    7  HPFS/NTFS
/dev/sda3            1288        8937    61440000    7  HPFS/NTFS
/dev/sda4            8937       38914   240793276+   f  W95 Ext'd (LBA)
/dev/sda5            8937       35076   209960932+   7  HPFS/NTFS
/dev/sda6           35076       38750    29508608   83  Linux
/dev/sda7           38750       38914     1315832   82  Linux swap / Solaris

Any idea?
Also a curious observation is that I have /boot/grub/ both under / and in the windows partition used for storing files.

If you are using Ubuntu, you are probably using GRUB 1.98 - not GRUB legacy.

What is the contents of /boot/grub/grub.cfg?

I got frustrated and reinstalled Windows 7 so I don't have access to / partition at the moment and the two /boot/grub/ that I see in my both windows partitions do not contain any grub.cfg
I should just try to rescue my UBUNTU.
