Trying to make copy of the OS/'dd'/USB.
by Camello from LinuxQuestions.org on (#5PY84)
Hello,
I am trying to make a copy of the operating system. I have tried with Clonezilla and others, I just don't understand the procedures in those graphical forms.
Now I try it from the terminal with the 'dd' command I don't know if I will also be erring in understanding the instructions ... anyway, this is what I"m doing:
Code:@SolydXK:~$ sudo -i
[sudo] password for:
root@SolydXK:~# df

root@SolydXK:~#But after all this when I go to the Bios, the USB (which was previously formatted in FAT32 -- and it is 64GB/the OS is around the 17GB) is not recognizable.
Also the PC does not recognize the USB after the use of this command, it only recognized it before all this ...
Where can be my mistake, the 'dd' command used here is not the correct one...?
