OS copied from SSD to new NVMe SSD but won't start – puzzling issue
Hello everyone, I bought a new 1TB NVMe SSD and cloned my operating system from a 250GB SSD using Macrium Reflect. But I’m still having trouble booting from it. I’ve checked some suggestions about turning off CSM and similar settings, but nothing seems to help. It feels confusing, and I’m not sure what’s causing the issue. Should I try disabling Windows Secure Boot or is it better to reinstall Windows on the new drive?
Did you duplicate every partition from the source drive to the target? If yes, you didn’t need to adjust any BIOS configurations.
If OS is installed on a SATA device, only the SATA driver (such as StorAhci) is activated for booting, while the NVMe driver is postponed until later stages. To resolve this, boot Windows from your old SSD again and run the command: sc.exe config stornvme start=boot. This will enable the built-in NVMe driver during early startup. Afterward, re-clone the system to the new SSD. Be aware that a reboot might reset the driver activation. Also verify that partitions are correctly aligned, as this is crucial.
