Thanks Nicholas, you did some digging! Correct me though, if I am wrong and misunderstanding this thread... It appears that this is about how to make it possible to boot from an SSD, and the problem that is being addressed is the fact that the BIOS did not have a module for supporting AHCI, just for RAID. So the solution being presented was how to add the AHCI support to the BIOS. As I noted in my previous post, it appears that in my BIOS I do have the option to switch to AHCI, so apparently it seems this has been addressed by AMI and ASUS.
And as I also mentioned, I tried to switch to AHCI but it gave the boot loader for Windows 10 troubles and I was no longer able to boot up Windows 10. So I am not sure how to make these two OS's play nice with each other, and still looking for a workaround...
Marc... yes i did some more digging and found recent threads, confirming the bios update, and like you, cannot then boot win10 with AHCI. So this would now appear a windows/drive problem? maybe consult google again regarding nvme/ahci/raid/windows. If windows supports ahci then there will always be repair/reinstall if all else fails.
Windows doesn't boot in AHCI mode because Windows wasn't installed in AHCI mode, it was in IDE mode. If you switch, it won't boot. Instructions on how to do this are found by doing a Google search. So for testing I would take the Laptop out of RAID mode, forget about if Windows boots or not, switch to AHCI mode in the BIOS, and then see if the openSUSE installer loads.
Thanks Carlos, SDM for again responding... I did do a Google search, and am still looking for answers on this... I following one persons "cookbook" approach on how he solved this issue and ended up with an unbootable laptop! (He said to change the Storage Controller in the Device Manager from the Intel Chipset SATA Raid controller to the Microsoft Storage Spaces Controller which claims to be able to manage both RAID and AHCI.) That seemed reasonable, but it hosed the Windows 10 boot process so completely that even Microsoft's recovery/repair tools could not fix it. So now I am a bit leery... I managed to recover Windows 10 from the recovery partition but painful having to reinstall all my apps... (even the recovery disk I had made on a USB stick failed to get Windows back up an running) So my lesson is to be careful about changing Windows storage management drivers! I am confused about why ASUS is using a RAID controller setting in the BIOS for my laptop... I thought RAID was used with multiple drives to build in redundancy and recover-ability. But my laptop only has 2 drives, an SSD drive and a 7200RPM disk drive. So why is a RAID configuration being used? Is there something about SSD drives that I am missing? From my Google research it appears this is common on lots of different laptops that come with Windows pre-installed on systems with an SSD drive, but I can't find an explanation as to why.... I assume that a RAID controller still honors partition boundaries, so I will follow your advice tomorrow and try switching to the AHCI mode to see if Leap 42.2 installs that way.. I am kinda worried about what that means for the boot loader itself also. What do I tell YaST, when I get to the part, to do about creating and putting in a boot loader for openSuSE? I don't fully grok GRUB2 either, should I prevent it from creating a new MBR? Create a boot partition? Put it in the root partition? And I dunno what I will do to make this a dual boot laptop, if this works, other than perhaps have to make this change in the BIOS every time I want to switch OS's... Seems like a rather ugly solution... Forgive me if I am asking too many dumb questions, trying to grok all this is like drinking from a fire hose!
