my MBR was filled with zero
today i used a live cd version of linux and boot with it.
first i use this command:
" dd if=/dev/hda of=/mnt/hda.0 bs=512 count=1 "
and then this command on my computer :
" dd if=/mnt/0.0 of=/dev/hda bs=512 count=1 "
0.0 is a text file with all zeros and has 512 bytes size.
but i forgot to save "hda.0" on a floppy disk to restore it later on MBR and reboot my computer. so this file was fully lost.
now the MBR was filled with "0", and i missed all of my partitions and OSes on my computer.
is there any trick or software , etc to restore the original my boot sector and partitios table on my computer.
