Hello, Recently a service engineer from Acer was replacing my hard disk, and I don’t know exactly what he did, but he caused MBR issues in my nicely working hard disk. He then replaced it with a new hard disk. My issue here is, that while I was trying to restore MBR, I mistakenly ran “_ **diskpart clean** _” on the drive that originally contained my complete OS and the D drive. Now it shows 100 % free. I am now looking into how to restore the complete hard disk, I haven’t written anything after the “diskpart clean” command. This is very important because it contains many important documents and my developed software projects, and I have no clue on how to restore the OS, as well as the D drive(which should have the backup of C drive, but now is cleaned as well). Would somebody please help, it’s urgent and very very important for me, as there is my final year bachelor’s exam dependent on it. ---
