One thing you could try, is there a Secure Boot option in BIOS? Try disabling that.
i am not a windows expert but if the machine has a completely blank ssd in it its not going to boot up on its own
Hush, then. (-:
A bare SSD will not boot, correct; however if you’ve successfully run the W10 installer then the install process should make it bootable at the point where it tells you to remove the media.
I can only assume that the install went south somehow. Like I said, I’d try again but make sure to wipe the drive rather than any sort of variation on an “upgrade” install.
USB is worth trying – if nothing else, it’s considerably faster than DVD – but the actual process should be identical regardless of media. What did you use to burn the .ISO to disc?
