Bios seems to forget the Boot device every so often. The machine cn work for a while and boot up just fine, but out of nowhere, it will boot to the Bios. In the Bios, there is no Boot device to be found. Once I create a new one and point to the correct location on the hdd, all is fine for a while again.
Why is this happening, and how can I prevent the Bios from loosing the boot device?
