First off... I would like to apologize if I'm asking something that a search would pull up but I think my question is pretty unique in some ways. Here is my setup for a test system. I'm installing Acronis onto a system that will require multiple OS's for software testing purposes. This is what I have done so far. My drive is a single drive with 2 partitions. 1. Install XP w/ updates and Acronis and create Full Backup. 2. Boot Vista and format drive with drive tool within install. 3. Complete Vista install w/ updates and install Acronis and create Full backup. 4 Repeat steps for both XP64 and Vista64. Here are my questions. What is the best way to restore from any given OS to another OS? I looked at the step by step guide and the versions are off so there is some confusion. Do I just select the partition the OS is installed on only or do I have to do both the MBR and OS Partition? Keep in mind we create our image on a separate partition. There has been some uncertainty on how to perform these actions and I appreciate any help you guys can provide. Thanks again.
