Help-Boot device not found

[BisquTz]

Hi, just tried to submit a peice of work for uni when my laptop started to get slow and then crashed and restarted. Once it restarted it posted this

' Boot device not found, please install an operating system on your hard disk, hard disk  (3f0), f2 system diagnostics.'

I had windows 10 before this happened and never had any issues before

Can anyone help

Thanks

Go to this website https://www.microsoft.com/en-us/software-download/windows10 and download the tool and make sure you have a usb drive. Once you have that, install it on the usb drive. Make sure you use another computer to do this.

Sounds like your hard drive died.
