Dell PERC 5/i (Windows Install problems)

[zer0gravity]

I just flashed my Perc 5/i to the newest bios and have a RAID 0 set up with two 74gb raptors. I'm trying to install windows vista/2k8/even win 7 and they are all able to see that I have a raid of (one virtual disk 138gb) but when I click on it to install it yells and says "windows is unable determine if this computer contains a valid system volume" or something. I have checked my Perc setup and it seems to be ok, booting from the raid 0, I've checked my mobo settings and everythign seems to be ok, but still unable to install. I can format the disk in all the setups as well but still nothing.

I have downloaded a handfull of drivers from dell perc drivers to raptor drivers in order to see if that effects anything, but to no help.

Does it need a MBR?

What am I don't wrong?

Thanks

Did you initialize the drives in the Perc 5 Bios?

Late reply, maybe you got it sorted by now.
