Thanks for posting in our forum. We understand you need to install Windows 7* in your new SSD 600p series, however, the operating system is not detecting the drive.
First of all, we don't have NVMe* drivers for that specific SSD, because the drive works with native NVMe* drivers (Provided by the operating system). Unfortunately, Windows 7* does not come with the driver built in, like Windows 8.1* or Windows® 10, that's why there is a workaround you need to follow in order to properly install the OS, with the hotfix provided by Microsoft*.
We are working to get options so the Windows 7* can be installed properly. Have you considered maybe installing a different operating system? (Windows 8.1* or Windows® 10)
