HP Proliant DL360 G4 Setting HDDs to read-only

Hello! I bought a new HP Proliant DL360 G4 a couple days ago, and it's setting the hdd (I only have one) to read-only, therefore I can't install an os on it. I have clonezilla (linux live enviroment) to work with.
The drive is in RAID 0 because I can't turn RAID off, and the only other thing that has been changed is that I've turned iLo off because I have no need for it. If you need any other info just ask

Thanks for helping                                                                                                                                                    -InVaLiD
