I have a dell inspiron 15z (ultrabook) with two drives, one HDD (500 Go) and one SSD (32 Go) managed by a kind of raid 0 array called intel smart response, and Windows 8 already installed.
Dell allows the bios to disable the secure boot mode, but when I launch the ubuntu installer from a live cd, the install does not recognize any drive.
So I tried, as read on the web, to deactivate Intel smart response from the GUI in Windows 8, and to set the SATA mode to AHCI or to ATA (I tried both).
In both cases, it does not work. I just want to use ubuntu and remove (if possible) Windows.
What can I do? Should I format the bios and reinstall it from scratch?
