Install on raid setup

Hello guys,
I made a raid 0 setup through the disk management of windows of 2 320GB hdds, and now i want to install clean windows seven in my PC on those raid hdds.
I went till the disk selection for installing but it shows me 2 hdds of 640GB.. and i i try to install on them they tell me to change something in the bios.
Can anyone guide me how to install on a raid 0 hdd setup?

I believe that you cannot install Windows 7 on a software RAID 0 array.

Does your motherboard support RAID? On an Intel board with a SATA controller that supports RAID, the normal way to install would be to switch the controller to RAID mode (the other options would be IDE and AHCI). That will give you a RAID sub-BIOS that'll allow you to configure the disks as a RAID 0. (That will also eliminate the data that are on the drives.) Windows will see the array as a single drive.

I haven't done this since Vista. I'm not sure whether Win7 includes RAID drivers, but it has a lot more drivers than Vista did.

That's good, better than the motherboard RAID (also known to some as Fake RAID, as it's more software than hardware).

What RAID card is it?

I've never used a real RAID controller, but it must be like the motherboard type: configure the array in the (controller's) BIOS setup. That produces a single logical drive, to which you can install Windows.

My RAID card is VIA VT6421 RAID controller.
And BTW how do i configure the array in the bios?
I don't see any option to do that?

Why do you want RAID0 with Win7? You'll have no performance increase and no real redundancy since you lose everything if you lose one HD.

Better to install directly to your fastest HD on SATA1, then later plug in your other HD for storage including storing a Win7 backup image which provides real redundancy. Backup Complete Computer - Create an Image Backup

I agree with GregRocker on this one :

Installing your OS to a RAID0 is fraught with problems - we have seen several difficulties/failed installations (mine included) of this here on the forums over the last few weeks. My recommendation is to steer clear of this for the time being.

The card should have its own BIOS, separate from the PC's BIOS. There should be a screen during bootup that you enter via a hotkey that allows you to configure the array. (On a Syba card with your Via controller, it's the tab key.)

Do you get such a screen?

Well the main reason was to get faster speed and boot, and for installing games so that I can get an improvement on playing speed. But how come you people say that a HDD fails mostly in raid? At least till now none of my raid HDD has failed.

I'll check the bios screen a lil later ATM I have to go somewhere.
