Title:
  Can't boot into Windows 7 after install Ubuntu 12.10

Status in “grub2” package in Ubuntu:
  Expired

Bug description:
  This is the second time i encounter this problem. I have Windows 7 installed on Partition C on my Hard drive.
  When I tried to install Ubuntu 12.10, it detects that I have Windows 7 installation. I choose the option to install Ubuntu along side Windows 7 and let the installer do the work automatically. When installation finishes, I got the grub2 menu showing that normal Ubuntu choices and one entry for Windows 7. When I choose it, I got an error message that I can't boot into Windows. I didn't note the message but it talks about having invalid arguments for calling Windows 7 loader.

  After doing some researches on this problem, my major suspection is
  that Ubuntu overwrote the MBR records for Windows. It didn't create
  for itself another drive and installed its boot record!
