1) booting from installed ubuntu
2) open a terminal from Application→Accessories → Terminal and type:

sudo gedit /boot/grub/menu.lst

if the system ask you a password give your user password, you will not see nothing when you type it, then press enter

Modify save and exit

3) to discover your disk parttions please type in a terminal

sudo fdisk -l

if the system ask you a password give your user password, you will not see nothing when you type it, then press enter

in grub disks and partitions reference number are starting numbering from 0 zero...

So

/dev/sda -> hd0
/dev/sdb -> hd1

/dev/sda1 -> ( hd0,0 )
/dev/sda2 -> ( hd0,1 )

/dev/sdb1 -> ( hd1,0 )
/dev/sdb2 -> ( hd1,1 )

Hope this helps

you have to repair your windows7 MBR only
just run the win7 DVD and select repair then first option fix booting problem there after you will be able to boot into both the OSs
