You either need to reset the setup to disable IRST (RAID), enabling AHCI mode -- or you need to pause the Windows installation to insert the IRST driver from a flash drive.   F2 at setup to change the drive from IRST/RAID to AHCI mode, or the driver here: [URL]  
Hi, I do have an issue where the XPS 9510 was not detecting the SSD. I see in BIOS that SSD is OK. I try to run a supportassist OS recovery but it says: "either WLAN or LAN Network is enabled". I go back in BIOS WLAN is ON.I then try to load default config, but that does not fix the issue. I try now to reinstall BIOS from USB but the "select file" never opens. Please help me reinstall my windows! 
BIOS Corrupted?
