You may have to change some BIOS settings if your computer does not look to the CD before the HD for system booting. This CD is meant to “autoboot” meaning that when the CD is placed in the tray, and your computer is rebooted or turned off/on, the system will boot to the OS located on the CD.
Most of you are by now, familiar with “miniPE” and what it is about - this is a new version release with added/updated apps, and of course, all new virus defs.
