My laptop has a failing HDD. When I try to install Windows on it it says that it may fail soon, yet I install it anyway. It's almost 5 years old. Recently, I'm facing a new problem. I installed Windows 10 on it, fresh install. A few weeks later, Windows failed to start up. Start up repair failed too, even my efforts of repairing the bootrec or MBR through CMD went futile. I formatted the C:/ drive again, installed Windows 10, only to face this a few weeks later again. Is the failing HDD the problem, or could it be another reason? I do not want to replace the HDD with a new one spending 4k INR to realize that was not the problem.
