Installing Windows7 after Ubuntu 14.04, other recommendations not working

Question

I know this questions has been asked hundreds if not thousands of times, and I've actually successfully done this before, but I've tried several things on this system, and nothing has worked yet. Here is my setup and the methods I've tried.

Setup

I have two SSD's in my laptop.

/dev/sda - This is my storage ssd (1tb)

/dev/sdb - This is my ssd used for ubuntu and windows (500gb)

|_ /dev/sdb1 - This is my ubuntu 14.04 install

|_/dev/sdb2 - This is my Windows 7 install

I don't have a boot partition, it's on sdb1.

Method1

a. ) Resized my Ubuntu partition to make room for my windows 7 partition using gparted. I created the partition as NTFS, and installed windows 7 correctly. On reboot, the machine booted into windows 7 as expected.

b. ) I booted into an ubuntu live usb and used these instructions (the accepted answer).

sudo mount /dev/sdb1 /mnt
sudo rm -rf /boot # Yes it was the live usb /boot, not the sdb1 /boot
sudo ln -s /mnt/boot /boot

sudo apt-get update && sudo apt-get install grub-pc
sudo grub-install /dev/sdb
sudo umount /mnt
sudo reboot

Upon reboot, I now see grub, but only ubuntu is listed.

Method2

a.) I completely redid the windows 7 install, since I kind of regretted how small I made the partition. I then booted into windows 7 successfully.

b.) While in windows 7, I downloaded and installed EasyBCD, and tried to let it make the changes (I've done this before and it worked, but I really didn't want to do this again since I would much rather use grub).

After this method, when I reboot I got nothing but a 0 on the screen. Obviously something went wrong.

Method3

a.) I reinstalled windows 7 yet again, and decided to let a Linux utility try and solve my problem. I used boot-repair

sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

I then ran the recommended repair, and after reboot I got the exact same result as Method1. The reboot showed grub, but only ubuntu was listed.

Method4

a.) I assumed I made a mistake on one of the steps, and I went back and retraced my steps 3 times each. That sounds ridiculous, but I really didn't want to post a question on something so simple.

b.) I posted this ridiculous question on askubuntu.com. Any help is appreciated.

EDIT1

Along with Method1 and Method3, when trying to reinstall grub, I also tried this recommended method. I had the same thing happen, Grub works, but nothing shows but ubuntu.

Answer 1

Since the automatic ways aren't working, I tried googling for "manually add windows to grub" and found this.

The linked answer suggests the following:

The first step is to edit /etc/grub.d/40_custom (using SUDO) and add the following lines to the bottom of the file:

menuentry ‘Windows 7′ {
set root='(hd0,msdos2)’
chainloader +1 }

Then running

sudo update-grub2

Sadly I don't have personal experience with this solution though, just thought it might help. (it's also kind of old)
