This could be a semi-complicated issue. I have encountered a similar issue in the past where I had a Win 7 installation and installed Win 8 on a different disk then was unable to boot into Win 7 because installing Win 8 overwrote the Win 7 boot loader.
I suspect the issue is with your MBR (master boot record). If your Win 7 partition is not listed there, you will not be able to boot from there. It has nothing to do with Toshiba.

Also do more searching on Google for dual booting windows 7 and 8.
