I cloned Windows 10 C drive from a SATA SSD drive and put it into the M.2_1 slot. It appears in the storage configuration and bootable options. I enabled it as #1 choice.
The M.2 drive appears on the computer and can be used but the computer does not boot up from it. I disconnect the old C drive SATA SSd and on start up the computer says I have to connect a bootable device. The motherboard is an AB350 Pro4 and the new M.2 SSD is a Samsung 970 Evo Plus 2Tb. I looked it up and it came up as compatible with the motherboard. I want to change because I keep running out of space for new software on the old drive.

what efibootmgr displays for new device and what for the original one?
for windows it might been "bcdedit /enum firmware" or something |

Thanks for answering M440
I am not an expert and don't know how to find out about the bcdedit/enum. What I can say is that the SSD is found on the boot menu. However, the SSD is connected to the M.2_1 (PCIe) slot. Should I connect it to the M.2.2 (SATA) slot where the C drive is connected (SATA3_3) and disconnect the old drive? Would that work? |

cloning is not enough (that is provided you did a perfect disk copy including the disk EFI partition) the UEFI bios need to know where is efi boot file to make it a Boot entry.
Colloquially you can say that UEFI bios does not boot a drive, but EFI files on the drives. You have to do this manually using bcdedit or try the startup repair from the windows installation media. try doing this: https://www.youtube.com/watch?v=4awsXR8STUo I would remove the original disk you made the clone of, because this might confuse the process. |
