TensorFlow is an open-source, free software library that runs in Python. It provides dataflow and differentiable programming that is useful in Machine Learning and Google is major proponent of it. However, the installation instructions for Windows are not fully accurate and took me several hours to grind through line by line, error by error, omission by omission. The video below shows the results of our work and will get you to installing TensorFlow on Windows…
We explain, configure and install the Dell Ultra Speed Drive Quad NVMe M2 Disk PCIe Adapter using Windows Storage Spaces with Resiliant File System (ReFS).

If you install an M.2 drive into a PC there is a good chance that Windows and the BIOS will not see that disk. Most BIOS’ are configured for RAID even if there is only one disk.
