I have been unable to set up RAID 0 on a new Windows 7 system.
Both drives are identical, and are functioning. I set up RAID using the controller, reload the operating system, and on reboot it cant boot to the harddrives. In the BIOS I can not set the drive priority (the only option is "Not Installed").
And if you hit the CTRL+I can you create your RAID there then the BIOS should show RAID as a boot option.
I can create RAID there, but there is no RAID boot option.
I can set "SATA controller mode" to RAID
In the boot screen I can not set "HDD Group Boot Priority" to anything. The only option is "Not Installed"
Out of curiousity, if you choose the Advanced mode setup of Windows, can you see the hard drive size? Does it see both drives, or the entire RAID? Perhaps you need to load the RAID driver during the install process. I have ran into this before with Windows XP on one of my systems, where setup saw the drive and the RAID, installed fine, but could not boot to it.
