I am not responsible for any damage. I am not an expert, but could try this,

You need remove BIOS RAID metadata, you can to use dmraid command and remove the BIOS RAID metadata

[root@localhost ~]# dmraid -r -E /dev/sda
Do you really want to erase “??” ondisk metadata on /dev/sda ? [y/n] :y

tried "dmraid -r -E /dev/sda" it says "No raid disks"

Thanks, 1Answer. I don't have enough points to upvote you, but I would if I could. I've been stumped by this with both Ubuntu 12.10 and Fedora 17. Much appreciated!
