Is it possible to create a bootable software RAID0, RAID 5, or span with a Windows installation?
The answer is "NO".
One cannot start an OS from a software RAID0, RAID 5, or JBOD. A hardware controller is needed to do this.
It is not possible to boot off the software RAID for the RAID is not accessible until the operating system is done loading, and the operating system itself is on the RAID. The only option is to boot off a software RAID 1, and even that is not that simple. To boot from a "shadow" disk of a software RAID1, you probably need to copy the master boot record first.
