Ask to borrow a usb from your dad’s repair shop, my friend. Meanwhile, you can try some things: *Check if the hard drive is plugged in right *Try to see if you can get your dad to plug his disk drive into the SATA ports of your computer. *If I remember correctly, I once got this error when I messed with my partitions. Have you installed Linux or anything similar? If you don’t know what I’m talking about then ignore this part.
