May I add that with a recovery partition, you would not need to use Nero 7
as the very existence of such a partition put there by the manufacturer,
means that your system is capable of restoring this partition (copying it)
to your system partition (overwriting it) even when the XP operating system
has failed. The recovery option will have its own mini-operating system
and imaging software that starts up instead of XP.
Thus, you will find on the system you have has a message on booting it that
says something like "Press F2 for recovery options" but it could be any key
combination (but the F - number keys are the most common) .
Since you are on a working computer with internet access right now, I would
take this opportunity to look up "System Recovery" or "Recovery Partition"
on the dell website, after selecting your computer model type.
