Acer Slimtype Laptop displays no bootable device

My Acer laptop says no bootable device. I have tried to reboot it and used the different methods that I saw online to no avail. I have reconciled myself to the face that information has been lost but I would like to save my laptop. There were no recovery discs that came with it. What can I do to restore it to factory settings at least. It came with windows 8 and was upgraded to windows 10, I think. I am currently on the InsydeH2O setup utility screen and I think that the setting for each of them have been changed too. Is there anywhere I could find a solution to this problem? Thanks in advance.
