Windows 7: Can I switch my boot disk from ahci mode to raid mode?

Can I switch my boot disk from ahci mode to raid mode?

I Installed windows on a ssd drive running in ahci mode. I then switched the sata setting in the bios from ahci to raid in order to add 2 other hdds as a raid 0. Now the pc won't boot anymore getting no boot device error. I know about the registry fix to get an IDE sata drive to boot in ahci mode, is there a similar solution to change a dire from ahci to raid?
Note the mb only has 1 controller so I can't have the boot drive in ahci mode with the other 2 in raid mode.
Thanks in advance.

Hello Danag, and welcome to Sevenforums. What kind of computer do you have, or did you custom build it? Go to it's manufacturer's website and install the Raid drivers.

EDIT: set it to RAID after the Raid drivers are installed, it will be fine. Let me know how it goes

I just reinstalled windows on the ssd with the bios in raid mode. Annoying, but seems to be working so far.

You didn't mention the drives, but they need to be identical for a striped array. They also need to be configured together as an array before you install the OS.

That being said, given the cost, you'd be much better off spending your money elsewhere, as RAID0 on a desktop is nothing more than hope and hype. Add in the increased rick of data loss (3x in your case) and it just isn't worth it. Some will even tell you that seek times take a hit on an array, causing slower performance in certain areas of Windows usage. It was used early on to overcome the small size of SSDs, but now that they have fallen in price, the usefulness of RAID0 has pretty much pulled an Elvis, and left the building.
