Dual boot windows 7 and ubuntu 9.10 separate hard drives

[tatmark1]

I had vista and ubuntu dual booting on separate hard drives. I unplugged my ubuntu drive and installed windows 7 on the vista drive. I now have ubuntu drive plugged back inand now I am stuck.
It boots to windows 7 and i can switch drive is in bios and boot ubuntu drive and it starts with grub menu. The grub menu still has vista on it but will not boot 7. I would like to get back to booting with the grub menu if anyone can help.
Thanks

There are many posibilities that cause this problem.

Can't you mount the window volume file in ubuntu?
-If not, your Ubuntu is having troubles mounting the volume.

Then, in terminal type:

sudo fdisk -l

If you can mount the volume:-

try to install grub2..

sudo apt-get install grub2

then, try to update the grub2

sudo udate-grub2
