Try running this command in a terminal:
sudo update-grub

It will ask for your password.

Title:
  Windows7 missing after upgrading from 10.04 to 12.04

Status in “grub2” package in Ubuntu:
  New

Bug description:
  PC with dual-boot Windows7 /Ubuntu.

  After upgrading from 10.04 to 12.04, the grub menu went away (no GRUB
  menu at all, so no access to any OS).


  Remark : after reinstalling GRUB into the MBR of sdb, the grub menu came back, which restored access to Ubuntu.
  But still no access to Windows7.
