I don't know where *anyone* has gotten this stupid idea from so listen up real good: THIS CHANGE TO BOOT0 WILL NOT REQUIRE ANY SYSTEM TO EVER BE REINSTALLED. The change that's being made is to desupport the creation of incorrectly laid out 'dedicated' disks. Your existing layouts will continue to work just fine. You could never use MBR-based OS selector with any other dedicated disk, so you are not losing any more functionality. PLEASE STOP SPREADING FUD AND UNSUBSTANTIATED RUMOURS. THANKYOU. -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.
