I'm not sure I understand. Aford, you say that my drive needs to be enabled in the BIOS. Yet, if I can boot into 7, isn't it already?
The_Prophecy, I don't think my hard drive is RAID. But I'll check if it's set in RAID mode.
Booting from a CD or DVD in the optical drive can occur no matter what the drive controller mode is set to. If the controller is set to IDE (or Legacy - terms interchangeable in this case) mode, the drivers are already included on the Windows install disk, and thus you can see any hard drives attached to the system without having to do anything. As soon as you set the controller mode to AHCI or RAID, a different driver is required for Windows setup to see any hard drives attached to that controller. Quite often, the AHCI/RAID driver is not
included on the Windows setup disk. This changed with Windows 7, as many RAID drivers were included to make setting up the operating system easier for the end user. Given that fact... many RAID drivers were included, but not all
of them were.
