Hi
“System Recovery” can be done using HDD recovery procedure or the Recovery disk which can be created using the preinstalled tool called Toshiba Recovery Media creator. As far as I know this is mentioned in user manual.
To start the HDD recovery check this document:

I agree with Paolo… it looks like software bug so don’t be afraid that hardware is not ok…
