I have a Samsung R540 i3 which came with Win7 installed. After 2 years I decided to move to Ubuntu 12.04.

During the installation I tried to preserve C:/ unit with Win7 and installed Ubuntu beside, deleting D:/ unit.

Although ubuntu is running perfectly I've never been able since then to recover Win7, GRUB does't show after turning my computer on and if displayed manually with SHIFT no Windows installation is shown among the options.

Just in case I've recorded and attached the sudo fsidk -l info, hoping that gives you guys any clue. I'm afraid Win7 disk got somehow lost but if not I would much appreciate some help.
