Try using an external, or another DVD drive in the FFPS, the 700 had a lot of DVD drive issues that would cause installs to fail, 770 may have the same problem.
After replacing both HDDs to Seagate ST500DM009 and installing FFPS computer boots bios, and after couple of seconds, briefly shows “GRUB Loading stage2…” and reboots.
Discs are new and good. Windows installs on them… too good?
