There is one other thing you could try, but this does not apply to all Toshiba laptops. Follow these steps:
Make sure the computer is turned off
Remove any peripherals such an external mouse, keyboard, monitor, USB flash drive etc.
Make sure the Mains Adapter is plugged in and working.
Press and hold down the 0 (zero) key on the keyboard while powering on the computer. Release it when the recovery warning screen appears.
If the recovery process offers a choice of Operating Systems, select the appropriate one for you.
A warning screen appears, stating that when the recovery is executed all data will be deleted and rewritten.
Click Yes to continue.
When the Toshiba Recovery Wizard opens select "Recovery of Factory Software" or the appropriate option for your needs.
Continue to follow the directions restarting as necessary.
As far as creating a recovery disc, I am looking into that for you now.
