Our recovery ISO (more correctly a repair ISO), is not a free copy of Vista (or W7 - you don't say what your OS is). There are no installation files on it, just the environment necessary to repair broken boot files.
If your Toshiba recovery partition is missing (try holding down the zero key as you power-up), and they didn't provide (or you failed to make) a portable copy, then you have 3 options.
Buy recovery media from Toshiba if you want all the bundled extras.
Borrow a Vista/7 DVD from a friend and reinstall using your key, not the one on the DVD.
See if MS will give you a free copy.
