I'm trying to get a functional dual-boot of Ubuntu 14.04 and Windows 7 Home Premium. I began with a working Windows 7, then created a partition for Ubuntu. I thought I succeeded in installing Ubuntu on that partition, but it appeared corrupted, so I reinstalled from the CD, choosing "Erase Ubuntu 14.04 LTS and reinstall". At that time, my entire disk was formatted and all 500GB of my HDD were given to the Ubuntu partition, my Windows 7 partition was entirely erased.

At that point, I created a new partition for Windows using gparted and installed Windows 7 successfully in that partition. As expected, this erased the Ubuntu grub bootloader, and my laptop now boots exclusively into Windows. I've tried a number of solutions from the Live CD, including Boot Repair and attempting to run install-grub and update-grub.

The Boot Repair paste is here: http://paste.ubuntu.com/7476445 .
I don't know where to go from here; I feel like I've exhausted all of my options, and at this point what seemed to be a simple endeavor to dual-boot ended up with me over my head.

If anyone could help or point me in the right direction, I would really appreciate it.
Thank you!
