I used the Data Migration tool by Samsung to clone the content (Windows boot drive) of a Samsung SSD 850 Pro to a Samsung SSD 950 Pro. But I can't boot from it now.
Motherboard: GA-Z170X-Gaming-7 with F8 Bios version
Windows 10 Pro (1803)
Bios mode is UEFI
Drive partition is GPT
If I select the 950 Pro as boot device I get the following message
Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key
If I look into
Diskmgmt.msc the drive is offline with the following message:
This disk is offline, because it has a signature collision with another disk that is online.
I tried to unplug the old drive (850 Pro), but I still can't boot from the new SSD. Installing the Samsung NVME driver also didn't changed something. The device is still using the Intel driver. Samsung Magician can't correctly detect the device (sure, it's offline). I can set it to online mode to access the data, but I can't boot correctly from it.
It seems the boot sector is faulty. Do I have to reinstall Windows completely or can I get the cloned drive to work?
