Wrong ubuntu installation does not recognizes windows

Question

I had a dual boot installation ubuntu+windows that work just nice, but i messed up with ubuntu so much that i needed to reinstall it, and for some other reasons too, reinstallig was a good idea, so I did it. No I can not access windows because it does not shows up on grub. Already runned boot-repair but nothing. It seems that before reinstalling i should deleted the linux partition from windows and let the windows bootleader be the only one. How can I fix this problem? I've found pre installation instrunctions.

Thanks in advance.

Ubuntu 14.04

-- Edit --

Some details

Step 1. Be happy with ubuntu installed along side with windows

Step 2. Be bored so that I wanted to play arround ending up on screwing the ubuntu installation

Step 3. Care little about the installed OS and be so lazy to fix it so re install the ubuntu OS

Step 4. Finish installation all stuff required and notice that grub does not load your previous installation of windows (I didn't delete it.. just in case)

Step 5. Search the problem and found a lot of places saying that before re installing ubuntu you have to let windows be the boot loader so that ubuntu installation will detect it... (too late)

Step 6. Ask ubuntu :) (Solved by the way)

sudo fdisk -l

The out put of the command above, it is solved, but i have two entries for windows 8, would need another question maybe thought

Your problem isn't very clear, could you edit it and tell us what you did step by step. — WxPilot, Sep 21 '14 at 15:13
Run sudo fdisk -l and add this information to your question. — To Do, Sep 21 '14 at 15:23
Kind of same idea but the other way around, and the solution is simplier — jaxkodex, Sep 25 '14 at 13:46

Run at Ubuntu's terminal:

sudo update-grub

...and your Windows installation will be on Grub's list again... :)
