you missing /bootmgr , /boot/bcd files in windows 7 sda3 partition. why grub's os-prober in ubuntu cannot detect , why has not added windows entry grub menu. guess these files in freedos sda1 partition. did install windows 7 when freedos partition there? windows 7 installer has obsession sticking boot files anywhere c: partition , grab pre-existing suitable partition formatted microsoft filesystem.

1 odd thing i've noticed - have windows code in mbr. can boot ubuntu? have grub installed boot sector of sda, partition boot flag, perhaps how doing it. it's strange way of getting grub boot.

have windows 7 installation dvd (a microsoft one, not oem restore disc) or did create windows 7 repair cd while still able boot windows 7? if yes either, have here:

if boot installation dvd or repair cd , go command prompt, should able repair boot sector of sda3 either 'bootrec /fixboot' or 'bootrec /rebuildbcd'. don't use 'bootrec /fixmbr'. rewrite windows code mbr.

once you've repaired sda3 boot sector, boot ubuntu (if can) , run terminal:

code:

sudo update-grub

there few other loose ends, let's see does.

have wubi installation in windows sda3 partition, that's not problem @ moment.
