@Enthousiast So, in my BIOS... I don't know what this option is and whether it applies SATA mode 1. AHCI 2. INTEL RST PREMIUM ** ** ** If I enable UEFI... then, Network Stack option show up -- which has options to enable IPv4 and IPv6 network installs I suppose. Disabling UEFI makes those options disappear. No other options come on when UEFI is disabled. ** ** ** I do have on my TITLE and in one place I said my "other laptop". Anyway, yes, I am trying to do this on a laptop. It is probably an OEM laptop modded [I guess even in the MOBO or BIOS or whatever] to not show who the real suppliers of their parts are. So, you mean to say, I have to go the UEFI route? Which is fine. Ah that explains it, it can be UEFI only [as you say] and that is why, no other options are showing up.
