Installer not always cleaning properly the USB device

[equetzal]

Problem

Some times when installing huronOS to multiple USB drives I encounter the issue in which the filesystems are not completely re-written on the drive and I result in booting on the same previous system before the installation. This happens only when the USB drive already had huronOS installed with the same partition scheme as before (e.g. build 0026 and 0027).

I've not been able to repro this issue in a 100% basis, but it happens often, not sure on how this is triggered, but I would suggest zeroing each partition to delete their filesystem and then zero the device to delete the partition table, this way the installer is 100% sure there's no filesystems to recover this time and we can reliably be sure that after installer finishes the new system is present.
