Can I download a System Recovery/Restore online?

I crashed my sons’ computer. I was trying to uninstall Google Chrome (because the computer would shut down every time you tried to open it) and I am now unable to even get Windows to open. It now opens to a black screen and a system message saying something about copyright, check the cable connection and “No bootable device – Insert boot disk and press any key”.

Is there someplace online I can go to download the boot disk? I went to the Toshiba website, it has a bunch of downloads available. I’ve no idea if what I need is there or even available. I narrowed the search with the model number but I don’t know which one to choose (I’m thinking either an Application or Utility? none were titled ‘system’ though). The list is lengthy and I’m not even sure if I can download the drivers on my desktop, burn them to a CD, then use it to recover the system on his laptop.

I don’t know what to do when going in manually with the F keys. Plus if it’s possible I’d like to have the boot disc for future use. This is the third time it’s crashed (the first two times it was under warranty).

Any help is greatly appreciated.
