It's more likely that your hard drive is corrupt
I just got this issue a few days ago
had to buy a new hard drive...
or you could take it to a shop and it could be that you don't have a corrupted hard drive
You are using a lenovo laptop right?
Near the charging point there will be a little button press it go to bios and check the dialog written =Hard disk see if there is written not detected
if not there must be some kind of letters and numbers which is okay
