Hi, from my experience with Partition Magic on my dual boot configuration, I assume that the MathID is generated from the data on the root partition if you have no network card with a MAC address. Since the root partition does not change it seems impossible that you get a new MathID. But Mathematica can store the password on two places first in $TopDirectory/Configuration/Licensing/mathpass and second in your local preferences directory $PreferencesDirectory/Configuration/Licensing/mathpass I assume that you have installed Mathematica and enter the password as a root. Mathematica has (on my Mandrake 8.0) Linux the habit to write the password file into the preferences directory of the root and not into the global $TopDirectory/Configuration/Licensing/mathpass this hinder all other users to use Mathematica. Please login as root, look if you have a /home/root/Configuration/Licensing/mathpass and copy/move this file to /usr/local/mathematica/Configuration/Licensing/mathpass and ... hopefuly it will work.
