When You boot, do you get the the grub choice of operating systems, i.e Ubuntu, WinXp and Vista?

You overwrote the mbr when you installed Windows 7. To restore grub, get out your LiveCD and boot from it. Once at the desktop open an Applications-->Accessories-->Terminal and type:

sudo grub

Once at the grub prompt type:

find /boot/grub/stage1

This should result in something like this:

(hd0,1)

For the next step type:

root (hd0,1)

substitute the result of the find command for (hd0.1). Next type:

setup (hd0)

Use the result of the find command without the partition number. Once the command has run type:

quit

Reboot and you should have your grub menu back.
