I have a Dell Inspiron, 6 years old. I am fairly certain that the hard drive has failed. It will not boot and I have completed all
the normal testing...repair, diagnosis, restore points, safe mode etc and it will not boot. It came from the factory 6 years ago
with windows 7 preinstalled. I have since upgraded it to windows 10 and windows 10 was activated with microsoft. When I replace
the hard drive should I reinstall windows 7 or should I try to go directly to windows 10? If I reinstall windows 7 and get it working properly can I upgrade to windows 10 since windows 10 was on this machine recently and it was working okay. All this problem started about
1 week ago.
