Problem with newly purchased Toshiba laptop

I recently purchase a Toshiba laptop, I have been using it for almost a month now for work. Just recently while I was using it my laptop’s screen went black and there was a long beeping sound coming from it, seconds after it came back and then went black again bearing a message saying “no bootable device”. Can anyone help me deal with this issue or should I bring this back to the store where I purchased it since, it is still under warranty?
