Question Problem with new NVME and Gigabyte Bios

[SRock7]

I have a circa 2016 Gigabyte Z170 build which has been very solid over the years. My Samsung 1GB NVME m.2 boot drive has filled up and I am trying to replace it with a 2GB Samsung EVO 970. The original drive was a MBR drive. I used Acronis Clone disk on automatic (will only clone MBR to MBR) and successfully cloned the drive. When I boot it cannot find the new drive/operating system. When I go into the bios, the boot disk is generic disk and in the BBS priorities at the bottom of the list of disks is my 970 NVME but as I click on it it never seems to get selected. The CSM support is enabled , Windows 8/10 is selected Storage boot is Legacy , Other PCI device is Legacy . Fast Boot is disabled.
If I go to the save page it asks if I want to use a one time alternate boot and if I choose the New disk it successfully boots into Windows 10.

When I put my old NVME disk in it gets chosen and boots.

Any help appreciated

Try disabling CSM and boot with the new disk. Chances are it shipped with gpt and not MBR. You might also need to clear the secure boot keys.

Turns out (as is usually the case) its a combo of user error and a bad interface. I have gone into the older Gigabyte (2016) interface maybe 25 time in the last 2 or three days and yet I never tumbled to the fact that you could if you wished with this interface establish a first boot (i.e. cd rom) a second boot if that failed, a third boot if that failed up to a max of the number of devices you have installed. I use 10 letters (an NVME , 4 storage drives and a bunch of USB letters for an installed card reader). The new NVME showed up initially in position 10 ( the last device installed) and I kept trying to change it by clicking on position 10. All I had to do was click on Storage position 1 (DUH) and change that to the NVME and reboot and it came up immediately!

To be fair, it is a non intuitive interface, but still it was there in front of my face.

Thanks for taking the time to try to help me out!

Yeah, there's a ton of boot options these days with the number of ports increasing in some boards. I disable all of them and only leave the boot drive enabled on mine. If I need to rescue it with a USB I'll hit the F key for that. I didn't think of boot order as a cloned replacement should takeover the top slot I would think.
