never posted before. did a search and found this forum. thanks for the info.
Which info do you mean?
I have indeed tried both, and with the NVMe.zip guide it boots and shows it in the PCIe devices list, but not under boot options, and with extracting the file from modded bios and changing it for my ssd, flashing the bios with it would freeze the PC on boot, would not even let me go to bios unless I remove the SSD card.

What boots (the NVMe SSD or your previously used SATA disk drive)?
If you are should be able to boot off the NVMe SSD, everything is fine. Maybe the Master Boot Record (MBR) is missing on the NVMe SSD, but can be created by doing a fresh OS install via USB Flash Drive.
