Yesterday, I used this command to correct my MBR on my working computer,
$ dd if=/somefile of=/dev/sda bs=512 count=1
But very unfortunately, I used a wrong file. Now when I boot my
working computer, it says:
Non-system disk or disk error
replace and strike any key when ready
I think the partition table is destroyed. How can I restore my disk?
