Hello, please notice I`m new and I`m German - so please excuse my bad english. System: Intel Dual Core Acronis True Image Acronis Disk Director Suite 2611 What I want: I have two HDD (SATA) On the first I would like to have 3 primary partitionen.- 3 Times Vista x64 On the second I would like to have 1 primary partition with XP and 1 partition for data. Boot to each over OS Selector. Problem: Playing around I installed 2 Vista on one HDD with Os Selector. Result: OS Selector saw both installation. Booting the first, Vista comes up with his own bootmanager. If I choise then the first OS -then Vista works. If I choise the second Vista by OS Selector-again Vista bootmanager comes up. Now it makes no different, if I choise the first or second entry - no OS works.(missing bootfiles or something else) If I change entries in OS Selector for the second partition (bootfile in the first partition) ,then I can boot the second partition using OS Selector and the second entry in the Vista bootmanager. Problem seems to be That Vista installed for both Vista the bootfile in the first Vista partition. Also why comes Vista after booting with OS Selector with his own bootmanager up. Has anyone experience with my problems- please explain to me ! And how can I reach the goal ( see " what I want " ) ?
