Windows 7 Will Not Boot From New SSD


I recently installed a new SSD on my Macbook Pro 2011 - 13" (Sierra 10.12)

I followed all steps correctly using Winclone. When I hold the option key to boot into Windows 7, I get “error loading operating system.” Since this is a Legacy issue I hear, I force EFI booting by disabling the SIP. I try to boot to Windows 7 once more, and this results in a blank screen and still doesn’t boot Windows 7.

I have verified that the partition is GPT formatted.

I still have the winclone image saved on an external hardrive.

I’m running out of options. Please someone help me!

Does it show a specific error when it blue screens? This will help determine what to do next.
