I have an XPS 15 (L521X) with a 1TB HDD and 32GB SSD card. I wanted to perform a clean Installation to use the ssd as cache and I can´t access the RAID menu (CTRL+I) during boot even though SATA mode in my BIOS is set to "Intel Smart Response Technology". I had try a lot of things like wiping both disks, updating to the latest A16 BIOS and still can´t access to Raid menu.
Any suggestions are welcome!!!!
