I'm trying to setup a RAID0 with 2 new 300 gig Velociraptor drives on a Win7 64 bit system. Everytime I get to the point where I have to choose the drive to install the OS on, nothing pops up. I'm forced to disable raid and just install Windows7 normally. Anything else you need to know to help me figure this out? Thanks.
Have you set your HDDs to RAID in the BIOS? If not, do so, save and exit. At POST enter the BIOS again to define your RAID volume (usually ctrl+I on the RAID screen). Save and exit. Boot to the installation media.
