You have no Windows installation to add, unless it's on a disk that's disconnected or otherwise invisible. Chances are you accidentally wiped it out. If you have critical personal data on your hard disk, STOP USING UBUNTU IMMEDIATELY! You may be able to recover some of your data with the help of PhotoRec or something similar, but this is likely to be a tedious task. You'll also need a spare disk to hold the recovered files.

I'm sorry to be the bearer of bad news, but unless you have a second disk that's not showing up in Boot Repair for some reason, it looks like Windows is gone.

Incidentally, pasting the Boot Info Script/Boot Repair output in your question is redundant with providing the pastebin link, and makes your question harder to read. I won't edit your question to remove the redundant output, but you might want to keep this in mind in the future.
