Solution 1:

The software RAID solution is Windows itself: SFS refers to a "dynamic disk" in Windows 2000 or later, and software RAID volumes in Windows must be built on dynamic disks.

What I would do:

  1. Capture offline images of all drives before attempting to boot, to ensure that we do not make anything worse than it already is.

  2. Put the bootable NTFS drive on the first SATA port and the rest of the drives on other SATA ports, boot the machine, and see what comes up in Disk Management.
