What sort of storage device do you have? HDD or SSD? If HDD how old it is?
The reason I ask is I have a desktop PC which suffered from recurring "Windows can't load" errors. The root cause was a failing HDD.
Best to trouble shoot properly otherwise a reload of Windows will end up with problems again.
Thanks, the storage is an HDD and the drive is about 5 years old. I agree that the next step is for the hard drive to be properly tested.
