I have a PC with XP Pro installed and will be adding Vista shortly (initially RC1 but then an upgrade copy) on a new HDD. Currently i image my C (XP) Drive to my D (Backup) Drive. I'll be adding a V (Vista) Drive and upgrading to ATI 10. Once the PC is set up with both OSs what is the best way to image the PC? 1) Image both C and V Drives in one Image file to the D Drive 2) Image each C and V Drives separately to the D Drive. I think 1 is better because it does both in one job but what if (for some reason) i only want to restore one OS? Can i do this? Example: 9 am Boot into XP install upgrade / update / something 10 am Boot into Vista do same 11 am Boot into XP & discover XP unbootable / slow / crashes - suspect upgrade / update etc If i do option 1 will i be able to select to only restore the C Drive and leave the V drive as it is? If so, would there be any impact - i.e. to the Boot Loader? If i do option 2 i assume that i can restore the disks individually but will there be any impact?
