There is now a way to install F11 x64 or i686 on a Nvidia or Intel ICH10R RAID that was initially created using Windows. Install Fedora 9 x64 or i686 from the Full install DVD. Partition as needed. Once that is complete, use a minimal install set for Fedora 9. We do this for the ability to slice the partitions safely. Next use a F11 DVD to install on the existing partition and select format the existing partition. Do NOT delete the existing partition or you will end up with a segmentation fault in Anaconda. It has been a long time coming and this is not an elegant solution but you can now have F11 installed on an NVIDIA C55 chip set RAID or INTEL ICH10R chip set RAID that was originally formatted or configured using Windows. The change is dramatic. F11 boots on my E8400 Core 2 Duo 20 seconds faster with F11 than with F10. Fedora 10 will never get fixed for this issue. Fedora 13 is doing a fair job without workarounds.
