Go into setup (F2 at powerup) and change the drive from IRST (Intel Rapid Storage) to AHCI mode. You can then install Windows 10 without needing the rapid storage driver. If you want to leave the drive in IRST mode, you may need an updated Windows 10 install media set -- depending on what version of the installer you're using, it may be too old for the IRST driver you're trying to use.  
I have brand new Inspiron 15 3511 w/512GB NVMe and I am looking to apply my own Win 10 Ent LTSC from USB. Machine comes with Win 10 Pro. I have tried upgrading within Windows without success, F12 boot installation (adding Intel storage driver to see Primary drive list) without success and even Data wiped drive and still no success. Always ends in recovery error. iaStorAfs.sys file missing Error code 0x0000098 [IMAGE]
Have you successfully installed a fresh copy of Win 10 Enterprise on Inspiron 
15 3511?
