Not only will this not work from a technical standpoint, with the Toshiba restore media installing drivers for the Toshiba model you have, which will be very different from your desktop, this would also be at least two separate violations of the Windows EULA. Specifically that you have a volume OEM copy, and OEM copies of Windows do not contain transfer rights. Secondly, that the EULA clearly states you are allowed a SINGLE copy on a SINGLE computer.
So you have a technical issue and a legal issue. You will have to actually buy Windows 7. You can either buy it retail, or if you're willing to accept the limitation of the license being tied to the hardware it was first activated on, you can get OEM copies from NewEgg or on eBay for less than a retail copy.
There are problems with both luki19979 and mscathy's suggestions.
The ISOs mentioned will still require that you have a valid license for the software. You can't just download the ISO, install it, and expect not to need a product key. Well, I suppose you can, but you'll be disappointed.
Migrating an OS is also not really an option for the same reasons I already listed. First off, you have a completely different set of hardware, so the drivers will be causing problems. Secondly, you still have the legal issue of the migrated OS being unlicensed, or pirated.
