I have recently put together a new high-end gaming / work PC.

The relevant hardware items for this problem are as follows:

1 x ASUS Maximus IV Extreme-Z Intel Motherboard
2 x Western Digital Caviar Black 1TB 6Gb/s 
1 x Western Digital Caviar Green 750GB 3Gb/s
1 x Crucial M4 256GB SSD (Win 7 Here)
1 x Intel Core i7-2600K Sandy Bridge 3.4GHz

I have the hard drives set up as follows:

Marvel Sata Controller:

0->Western Digital Green
1->M4 SSD (Boot Disk With Windows 7)

Intel Sata Controller:

0->Black Drive (raid 0 Member)
1->Black Drive (raid 0 Member)

The Problem:

If the Intel Controller is set to Raid, Windows 7 will not boot (Even though Win 7 is on the other controller). I get a "Please insert proper boot item" error.

Before anyone asks, I ensured that the proper boot order was selected. My bios even allows me to select a device and immediately boot from that device - I still got the error when selecting the M4.

As soon as I change the Intel controller to AHCI mode, the system boots normally.

anyone know what's going on? I updated the mobo and sata drivers and still nothing.

Note: I forgot that my caviar black drives are 6Gb/s hence I would like to make use of all 4 of my 6.0Gb/s connections.

Why do you use the Marvel controller for the SSD? External controller never as fast as the chipset controller. My advice: Only use 6 SATA ports of the chipset and disable the Marvel - it's useless. There is no speed loss but a you gain much more less problems. – Robert Oct 13 '11 at 15:21
I have 8 SATA Drives. 4 are 6gb/s and 4 are 3gb/s Unfortunately 2 of the 6gb/s are from the Marvel Controller. I did not want to use the Marvel controller for raid so I put the SSD on there instead. – user993735 Oct 13 '11 at 15:30

YOu have only one device where it makes a difference if you use SATA6Gb or not: The SSD. All other devices are so slow that it makes exactly no difference if you use SATA6Gb or not. – Robert Oct 13 '11 at 17:57
