Macbook pro mid 2009 windows 7 64 bits

Hi to all,
I buy a new SSD for my mac. In my previous drive (250 GB ) I had installed Mavericks OS X and Windows 7 64 bits, everything cool until here.
I install Mavericks OS X in my new Drive, the OS X found the previous Windows 7 and still I'm able to boot (in the old drive), then I installed windows 8.1 in the new SSD (with the OS X), but I was getting to many errors and blue screen so I decide to install windows 7 in the SSD disk, but now when I create the USB install (with windows 7) I can't boot from USB, I try some suggestion but still I'm unable to install W7 in the new SSD disk.

What can I do to install W7? still I can delete all content from SSD disk but now from the old disk.

Thanks in advance,
Regards.

Well,
At the end after search a lot and following some guides, I could install windows 8.1.
The main issue is with the Bootcamp version and the NVidia display (windows 8.1 does not like the NVidia drivers I must disable to get a stable installation).
I use the the 5.0.5033 and almost everything is working fine.

If anybody can help me with the display issue will be great.

Regards.
