Specific steps for a successful clone operation: Or do I make a Win 10 recovery USB and try and force a boot partition on the new SSD? I've tried everything I could read on the topic, and consider myself at least borderline competent, but I'm lost.īut the very first thing you must do at the end of the clone process is to power off, disconnect the old drive, and allow the system to try to boot up with only the new drive connected. Should I try another software to clone it? It still could be a missed BIOS setting, though I feel like I've tried every combo. The new NVMe drive now shows in BIOS as a storage device along with my two storage HDDs, and works perfectly well in Windows if I reinstall the SATA and roll back the BIOS changes to allow legacy. I disabled CSM, and even reset CMOD by removing the battery for 5 minutes (after lots of other attempted fixes). I then used Macrium software to clone my SATA SSD (MBR) to my NVMe (GPT), and updated to BIOS settings to UEFI only, no legacy, and removed the SATA. At this point my BIOS was using a mix of legacy and UEFI. The new drive was installed and booted without issue after the update. In order to be able to boot with the NVMe drive installed, I updated my ASUS STRIX 570-E motherboard (Running 3900x).

I have Win 10 on an old Samsung EVO 850 256GB drive, so I bought a new M.2 PCIe gen 4.0 SSD (2 TB WD SN850).
