Hi @abdellm, since you mentioned that your laptop has encountered a hard / drop shock, most probably the hard drive is damaged. Try accessing the laptop BIOS and check if there are any diagnostic test for HDD. If the laptop is still under warranty, send in for service. else you will need to replace the HDD, just follow ifixit instructions for it, if you have some budget, go for SSD drives.
