Is it possible to create a bootable software RAID0, RAID 5, or spanned volume containing a Windows installation?
Unfortunately, no. It is not possible to boot from a software RAID0, RAID5, or spanned volume. A hardware RAID controller is required to do this.
You cannot start an OS from the software RAID because the RAID is not accessible until the OS is fully started up, and the operating system itself is on the array.
