Apparently when you rebooted during the middle of a partition operation ... always a very dangerous thing to do ... you corrupted the partition table in your Master Boot Record (MBR).
The BootInfo summary which was created when you ran
boot-repair shows the output below from
fdisk starting around line 478 of your pastebin.

While I am not sure what is the precise meaning of the message
omitting empty partition (5), this answer on SuperUser which in turn links to this post in the Ubuntu forums where it is claimed that
- Any time fdisk reports "omitting empty partition (X)", unfortunately that is a
sure sign that your partition table is corrupt ...

This may be why you can not boot Windows 7. I think the Windows boot process still relies on the values in the MBR partition table being "correct". I think it just gives up if things don't "look right".
I am not sure what to suggest. The obvious first thing would be to create whatever type of a backup you can before you risk doing something that may increase your drive's corruption rather than repairing it.
After trying to save your data "just in case" you might try using
You should be able to boot your Live USB and then install testdisk with
sudo apt-get install testdisk.
I would suggest starting with
sudo testdisk -l /dev/sda just to see what it returns. After that perhaps the "TestDisk Step By Step" web page might help?
