I've had this laptop for more or less 6 months, suddenly it crashed and now when I turn it on it says no bootable device. If I alt + f10 I get a screen saying that the default boot device is missing or the boot failed, and in the boot manager both the legacy cd rom and the legacy hard drive appear as "unknown device: unknown device:"
Is there any solution to this without having it repaired? Or is it a hardware problem?
