Windows7 is broken after installing 12.04 on a SFS disk

[Patrick]

I installed 12.04 alongside a preinstalled Windows7 via the CD Ubuntu (I used the option to install Ubuntu near Windows GRUB on sda) Now Ubuntu is ok, but Windows does not start from GRUB entry. Reinstalling GRUB does not solve the problem.
