Thanks for the reply.
Unfortunately I've already moved beyond this, but I'll fill you in on the background in thaw hopes that it'll contribute to the knowledge base.
My MSI (K9NU Neo-V) mobo died, through which I was running my OS & apps on RAID 0 (on board nVidia/Uli M1697 chipset). Most of my important data was on a non-RAID drive, but a couple annoying things (Outlook .pst, and some game saves) were on the RAID array.
The new mobo didn't automatically recognize the array (at this point I had rescued my data using raid recovery program, and was just looking to avoid the hassle of reinstalling OS, games, apps, etc.
I read in another forum/tutorial that I might be able to rebuild the RAID array without disturbing the MFT, as long as I knew the disk order and stripe size (I did).
I did this on the new mobo (that also was running nVidia chipset, but of more recent vintage) and tried a repair install to reset/rebuild the boot loader (if that's the right terminology, even with a "healthy" RAID I still wasn't booting). The interesting thing was that when it was time to load the RAID drivers
in the repair, I was able to browse the Computer and see/access all the files in the array.
Installation wasn't acknowledging the presence of an OS, but it was all there. I was hopeful that I could get the install to work, but was continually stymied by "the drivers failed to load". I was able to locate them easily on the USB drive and have the installer list the appropriate ones, but after a minute or two of the computer clicking away and the progress slider shooting across the screen, the error message was the only reward.
So I finally said "F***-it" and proceeded with a clean install.
Bottom line: no resolution, but an unwanted learning experience.
Sorry for the long post. I'm happy to elaborate on anything I've written, but you can consider me resolved.
Too bad I couldn't try your suggestions.
