Pay attention:
1.You have to find out whether your mainboard is NVME-capable at all. Most old mainboards should have received BIOS updates in early 2015 that add NVME functionality. But you have to check that on the manufacturer's website!
2.To add an NVME drive as Windows boot you need both BIOS support for NVME boot and a recent version of the OS that has inbuilt NVME drivers.
3.For Windows that means you need Windows 8.1 or 10 to easily install this as a boot drive. 4.A litter tips:Maybe was impossible to find the right drivers if the Windows 7 updates stopped.You can try to dual boot with Windows 10.
