Linux Parted question (fwd)

[Georgina Joyce]

Hi

We just discussed using dd on a mbr.  writing to 512 bytes destroys the
partition table as well as the MBR.  Kerry suggests 446.  But this would
make your MS OS unbootable.  From memory of your question.  If you
install a linux distro and putting the grub signature in the master boot
record, this will overwrite any virus residing there.

four kinds of freedom, for the users of the software:

    * The freedom to run the program, for any purpose (freedom 0).
    * The freedom to study how the program works, and adapt it to your
needs (freedom 1). Access to the source code is a precondition for this.
    * The freedom to redistribute copies so you can help your neighbor
(freedom 2).
    * The freedom to improve the program, and release your improvements
to the public, so that the whole community benefits (freedom 3). Access
to the source code is a precondition for this.
