Here is your manual which contains all your info http://support.dell.com/support/edocs/systems/xps410/en/OM_EN/YH251A02.pdf. Just to clarify the procedure anyway: enter your bios and under drives, sata operation, raid is off. Save info and reboot to optical drive and reload op system.

Hi DCX4EVER:

Thanks for the reply.

I thought it would be something that is so easy I would screw it up. Had to make sure though, can't post for help after deleting the OS.

Thanks again

The F6 key is associated with installing SATA HDD controller/driver

You don’t mention if you are using RAID 0 or Raid 1 (or anther RAID type config)?

Anyhow, you may find the following thread helpful, click here

Hello Bell Boy,

Back in 2006 my XPS410 was originally set up with RAID 1, the mirror hard drive set up, which is when one hard drive is an exact copy (mirror) of the other hard drive. The 2 disks were changed to a Non-RAID disk configuration in 2007 making them independent of one another. I also have multiple partitions on each drive now,  so defragging takes a minimal time and also makes it super easy to reinstall the OS every six months. I love the high speed performance of a crisp new install. And by keeping the OS in one partition and my personal files in another just makes things so easy!

So for the last 2 years I've been seeing the RAID splash screen prior to Window's splash screen. It shows that I have 2 Non-RAID drives. I haven't done anything with it but after 2 years of not using RAID I decided I may as well delete it to save time at boot up. If I want to use a RAID set-up again, I believe I should be able to re-install RAID controller/drivers (if necessary) at the OS install time by using the F6 key like you mentioned above.

Thanks for your help and links, they will be put to good use.
