First, thanks to all who responded to my earler message about this issue. Your comments, suggestions and recommendations were much appreciated.
Several of you made reference to the contents of the computer . The motherboard is a Gigabyte B850M with an AMD Ryzen 59600 6-core processor, both purchased and installed in September 2026. It is yet to have anything in it. Memory size 32768MB. The BIOS has six sections. Favourites, Tweakers, Settings, System Info, Boot and Save&Exit. In the Boot section there is indeed a 'Secure Boot Mode' which I disabled. When I was ready to 'Save and Exit' the 'Secure Boot Mode' changed to 'Boot override'. The colour changed to orange from white. The result? After 'saving and exiting', a return to the BIOS. The one difference in the BIOS that I found is under the Settings sections in USB configuration 'Genetic STORAGE DEVICE 0569... CD-ROM'. A footnote reads 'Optical drives are emulated (?) as CDROM. What would any of you suggest that I do next?
