Sata expansion card prevents windows from booting


Feb 25, 2012

I recently purchased an Orico PCI-E SATA III expansion card (PAS3062-2S). I installed the card on a Windows 7 x64 machine, with an ASRock Z68M/USB3 motherboard.

I could install the card no problem, everything worked fine – I could reboot my computer, after driver install, no problem.

Then, I connected a hard drive. Restarted my computer, and it would not boot. The BIOS passes with no problem, but windows will not boot.

Disconnect the drive, and the computer will boot.

It is not a problem with the drive, as it works in one of the SATA ports on the motherboard. Seems whenever I connect any drive to the PAS3062-2S it does not allow the computer to boot.

Why? I honestly have no idea what is causing the problem. Seems to be some kind of conflict, but I can’t get Windows to boot to resolve it…and in all honesty, I have no idea how to resolve it.

Thanks in advance for your help.....
Try going into the boot sequence in the bios and making sure that when a hard drive is connected to the card that the drive with the OS on it is listed first. Since it is a raid card it may be overriding the boot sequence so that the raid setup is booted first , even though you don't have a raid setup the cards software is designed to recognize whem a hdd is connected to then override the boot sequence.
