If I install a new HDD on my X-BOX and use Slayer's Autoinstaller to format and setup my new HDD will I also have the MS Dashboard?
Yes it allows you to boot to the M$ dash. I'd remind you to disable the chip for going on live but if you already signed up with the stock hdd, you'll get banned if you log on with the new hdd. The hdd info is embedded in the eeprom and live is now checking it.
