I have 2 identical disks (1 & 2). Only disk 1 has Vista & data on it - disk 2 was empty. Backed up disk 1 - MBR, Track 0, C:, D: (apps), E: (docs), and F: (empty). I created drive F: on disk 1 to backup the image file to. Wanted to then restore to Disk 2, hoping to test if would boot. Would either have to remove 1st disk before reboot, or disable it in BIOS (turns out my BIOS won't allow disabling). I used the rescue disk to do restore, at suggestion of beginner's guide on this forum. Q1: What *should* I have chosen as to drive letter assignment for this case in restore setup? Of course, ATI assigned drive letters of G:, H:, I:, and J: when it restored the orig partitions to disk 2. Obviously, I need the drive letters on disk 2 to be C:, D:, E: & F:, just like orig on disk 1, so it'll boot. Windows disk mgr wouldn't change the drive letter of the restored OS partition on disk 2 from G: to C: (logically). Q2: What change, if any, should I have made for partition type (primary, active, etc.) during restore setup? That's ASSUMING I removed disk 1 & didn't boot w/ 2 active, primary partitions (on disk 1 & 2). Instructions warn against that!!! I can just erase the disk 2 & do the restore again - but THIS TIME w/ the right settings. Could also (just for this test) use some other disk mgr to (possibly) change settings (active, hidden) and drive letters. Thanks! This is taking a while!
