Is this something Windows is telling you, or some type of built in software Toshiba provides?

In case Windows does not boot, you should be able to enter the recovery environment.

From Troubleshoot you can go to System Restore, Safe Mode, Startup repair ("Automatic Repair"), a command prompt, the BIOS/UEFI, or even restore the hard disk to its original out-of-the-box contents from the recovery partition..



According to Microsoft, trying and failing to boot several times will eventually take you to the recovery environment instead. According to Toshiba, you can also get there by pressing F2 or the zero key on powering up.

If you have completely shut down, Toshiba says you can get there using F12 to reach the UEFI boot menu and then selecting HDD Recovery. One might expect that to take you to Toshiba's recovery back to factory-new, but it actually leads to the recovery environment above.

Please try these out many, many times and let us know what happens.
