[leandrodafontoura]

I have windows 7 and a single RAID HDD. I want to convert the HDD to non-RAID, so I use with windows. How do I do that under the OS? I was unsucesfull in doing so in BIOS.

Before changing the bios setting, you must enable the AHCI driver in the registry. This is a good guide in the first answer here: http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/changing-from-raid-to-ahci/4c94f678-6bd1-48a6-b871-8872c841023a?auth=1
