how to get dual boot with windows 7 working

I'm currently having Ubuntu installed on a 120GB SSD. I have recently installed Windows 7 on a second hard drive (1 TB WD). After installing Windows, I changed the Boot order in the BIOS so that I can continue to boot into Linux.
I thought I can get the dual boot setup simply by running the Boot-Repair usb at startup. But that did not work out as easy as i thought and it is giving the below error -
=================== Repair blocked
GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again.
Alternatively, you can retry after activating the [Separate /boot/efi partition:] option.
Detailed log can be found here - http://paste.ubuntu.com/p/P9d3r67nKY/
So, my question is where and how do i create this BIOS-Boot partition ? I have run the Gparted as suggested by the Boot-Repair, but it doesn't let me do anything with the sda2 partition, probably because it is already mounted. Or is there some other way to get grub installed which can give me the dual boot menu options at startup ?
Thanks,
Bhaskar

You have Windows in BIOS boot mode & Ubuntu in UEFI boot mode. You can use that if you only want to boot from UEFI and change from UEFI to BIOS/CSM/Legacy for Windows. You can reinstall Windows in UEFI mode, if you copy DVD to flash drive and move/rename a few files to make it UEFI bootable. If you want to convert Ubuntu UEFI install to BIOS you have to use gparted to create a new small 1 or 2MB unformatted partition with the bios_grub flag & then reinstall grub in BIOS boot mode.
