Are there any external devices connected to it?

Customer: replied 1 year ago.
No just charging adapter. I did shut it down with a 2tb usb though.

Do you mean that the issue started when you plugged in a 2. TB USB?

Well no. I just had it connected into laptop as i pressed shut down button.Was trying to fix the usb which had been formated on xbox wrong and a suggestion from a forum was too shut pc down whilst usb was plugged in lol

Okay. Reboot the Toshiba and see if you can enter BIOS. Normally; it's the F2 key.

No bootable device -- insert boot disk and press any key
Expert:  Kamil Anwar replied 1 year ago.

Is there any disk in the CD ROM?

Customer: replied 1 year ago.
No
Expert:  Kamil Anwar replied 1 year ago.

Make sure HDD is the first boot able device set; and make sure secure boot is disabled.

Customer: replied 1 year ago.
Both settings are correct
Expert:  Kamil Anwar replied 1 year ago.

enable secure boot and change boot order back to UEFI. Then save the settings; and reboot. Power it off; take the battery out, unplug charger, hold power button for 10 seconds, put battery back in and reboot.

Customer: replied 1 year ago.
