Solved "Windows not installed on the drive from which it boots"

Hi Greg, let me explain again:
Where was this explained earlier? I repeatedly checked your original post for this RAID info.

Greg, you're right, sorry for that, my mistake.The reason for my confusion is that I posted separately the issue about cloning the RAID with Acronis (which initiated this related issue of bootmgr)

Did the cloning utility ask if you wanted C to be Active? That might explain why it became so.
No, Acronis TIH2014 did not prompt for that option

The installer will always attempt to plop the bootmgr on the largest partition it sees during installs. That's why when installing to a SSD is it important to disconnect HDDs since they are generally a lot bigger than the SSD is.
That's good to know!
