Screwed up Dual Boot Ubuntu/Windows 8 (for the umpteenth time!)

Okay so i installed ubuntu on my system which had Windows 8 pre-installed (Old comp so I'm sort of sure it didn't have secure boot and UEFI). I used the "Install alongside windows" option which promised to keep my windows files and programs untouched. The install went perfectly normal.

And now, when I boot, grub does not show up Windows option on boot! I can only boot into Ubuntu.

Things I've tried:

1) Using os-prober

2) Using update-grub (does not detect windows)

3) Using the boot-repair utility

Here's the complete Boot Info Script:

Can I do anything about it?

Whats worse, it replaced my D: and E: Windows partitions with a Linux Data Partition. Why would it do that?

Well there can only be two reasons - either you missed something while selecting the install alongside windows option, or it was a bug in the installer. Its strange that would happen, even on a UEFI system. You can check the installation logs from /var/log/installer which should tell you what it was doing step-by-step.

In any case, I suggest you restore your windows installation from a backup and if ubuntu's setup still attempts to overwrite the partition table then report a bug.
