    Hi, iam try to do a setup thats descripted in this how to:
    http://www.howtoforge.com/how-to-se...-system-incl-grub2-configuration-ubuntu-10.04

    But when i try to copy the partition table from /dev/sda to /dev/sdb with this code:

    Code:
    sfdisk -d /dev/sda | sfdisk --force /dev/sdb
    I get this error:
    Code:
    /dev/sdb: Permiso denegado 
    
    sfdisk: No se puede abrir /dev/sdb para lectura-escritura
    Atención: la partición extendida no empieza en un lÃ*mite de cilindro.
    DOS y Linux interpretarán el contenido de forma diferente.
    
    The system is in spanish, but the error says that /dev/sdb : permission deny
    and then : sfdidk : cant open /dev/sdb for read-write
    and then says: The extended partition not start in a cilinder limit. Dos and Linux can see the content of diferent way.

    Can anybody helpme? why i have this error?

    tnks and sorry about my english.
    bye

    SOLVED, like the editor not use "sudo" you have to used like this:

    Code:
    sudo sfdisk -d /dev/sda | sudo sfdisk --force /dev/sdb
    thks

    You must carry out all commands from that tutorial with root permissions. You can run
    Code:
    sudo su
    to become root.
