New User trying to follow Boot Manager install guidance

[philpense]

Have boot manager plpbt-5.0.14 downloaded to and unzipped to a Toshiba Satellite Pro that does not boot to USB.
Specs are: 2.66Ghz Processor/2.00GB memory.  Goal is to create option to boot to Ubuntu that is on a USB drive.  Have looked at the documentation more than once which are still not clear to me.  Hoping for step by step guidance from one who has done this

which version of windows do you use?

Much thanks for your timely reply.  The notebook has Windows 7 Ultimate.  I know that bootloader is required but the documentation could be misinterpreted.
