Booting from PCIe x4 NVME drive, cannot see previous SATA drives.

[ozeppelino]

After a long night, I finally upgraded my PC to a Samsung 960EVO NVMe boot drive on my Asus P8Z68-V/Gen3 motherboard. Windows is working fine, however, my old drives are not visible by the Windows installation (including drive management and diskpart). I can see the drives in the BIOS.

Do you know why I cannot see the SATA drives and what I need to do to make them visible?

Try re-setting the driver. In the Device Manager, uninstall the AHCI driver under Storage Controllers, and re-boot.

i used to have that board years ago

quite surprised a m2 booted on it to be honest seen newer boards than that one that couldnt

but on newer boards m2 drives can disable sata ports to get the pci-e lanes they need

so could have something to do with it

though thats a total guess as 5 or 6 year old boards like that just werent designed with m2 x4 pci-e drives in mind for obvious reasons

Thanks! This fixed it.

glad you got fixed

and nice to know that board can boot from a m2 drive

for future reference

thanks for the response! haha, that's why it was a long night. I had to hand modify the BIOS with files from a newer board to make it recognize the m2 drive as something I could boot from. The issue with the SATA drives just ended up being the AHCI drivers so thankfully everything is working great now!

a modded bios makes more sense not so surprised it booted now

but nice work on the bios mod

still nice to know it can be done with some effort

i really liked that board and my old 2600k at 5ghz
