I'm suspicous about why you're going back into BIOS after 3rd disk completes to change boot order. It would be better to leave it and just remove the disk. The reason is that a No OS error sounds like it's starting up to the wrong HD, and isn't any kind of error you'd get after just completing a 3 disk recovery.
Unplug all other HD's, leave the HD set first to boot and this time trigger the disks if necessary using the Acer F12 key at boot. But these disks should autostart on their own and prompt for the next one to autostart.
Run a quick Diskpart Clean Command to clean the bootsector before starting again.
And yes, the clean reinstall is a vastly superior install, nothing to feel you have to settle for.
