You can do a clean install of Windows on your new 2TB M.2 SSD and then once you have a successful boot on that drive, put your current M.2 SSD in the PCIe adapter to collect and move any files you want on the primary boot drive (if any).
I would like to upgrade the M2 boot drive. I currently have a 1TB NVMe drive. Can I just swap it with a 2TB drive? Also I am going to get a PCI to M.2 adapter. I hear the Aurora R11 will only support a 1TB drive when doing this. Can a larger capacity drive be used?
Aurora R11, upgrade M.2 1TB to 2TB drive?
