Your bios was set to raid, did you reset Bios to AHCI mode.
You can leave it in raid mode, But unless you plan on setting up a New raid0 with a pair of HDDs (I wouldn't). I would set bios back to AHCI. If You leave in raid you probably need to down load the "F6" rst driver (iaSTOR) can get from Intel.
Thank you! That allowed me to install. So just for reference,
P5Q3 Deluxe wifiAP@n mobo
1. Disconnected all drives except SSD on the ICH10R controller
2. burned W7 image to USB
3. Set BIOS to RAID mode
4. Began install and used diskpart to setup the disk so it would eliminate that pesky "windows cannot install message"
5. Load intel driver for this mobo (see intel's website for the ICH10R driver or download from asus)
6. If you use the Asus version, note that you must install the latest raid driver manually before you install IRST software...big oops...I had to reinstall. This is buried in the intel readme, but I r an engineer. I don't need instructions
7. enjoy the speedy SSD!
