Thank you for contacting our support community. As per our translator tool, we understand your situation regarding the Windows* Server 2012 R2 installation.
We would like to inform you that the Intel® SSD 750 Series is not intended to be in a server environment. We recommend you our Datacenter SSDs Family. However, for the installation process, we recommend you to load the NVMe* driver during the Windows* installation. The reason why you can not see the SSD is that the version of Windows* you are trying to install may not have the inbox NVMe* drivers as Windows* 8.1 or Windows(R) 10 do.
Please follow the next steps:
1-Download the 18.104.22.1682-Win32 -Datacenter.zip or the 22.214.171.1242-x64 -Datacenter.zip depending on the version you would like to install.
2-Extract the files and load them into a USB.
3-During the Windows* installation, on the option that asks for "where do you want to install Windows*?", please select the option that says load driver.
4-Select the Option that says "Browse" in order to locate the drivers in the specific USB you are using.
5-Select the Option that says Intel(R) Solid-State Drive P3700/P3600/P3500/750 Series and hit next.
After that, you would be able to install Windows* Server on your Intel® SSD 750 Series.
Please let us know the outcome of your situation.
