You asked if I could repair the Win7 boot partition. I repaired the Win7 MBR. The system -- both Win7 and Sabayon Linux -- then booted. So it looks like whatever corrupted the Win7 MBR also may have crippled Grub2. Even so, I was feeling pretty elated. The Titanic was starting to float again.
Glad to hear that.

And the reboot failed.
There is the saying Never change a running system, but that doesn't help you much.
I am curious. Is it possible for a loose SATA wire to somehow damage an MBR?
I guess so, your case seems to demonstrate that. If not all data are transmitted by the SATA cable, that could surely damage a MBR?
