I am interested to receive any feedback from Forum members with respect to practical experience of imaging/cloning any of the Vista OS versions. Assume that a user is operating under Vista and has created an image of the system partition and MBR of the physical disk where Vista has been installed. The user experiences an OS failure. They boot from the Acronis boot CD and rebuild the OS partition on the SAME physical disk as where Vista was originally installed (same Disk Signature and NT Drive Serial Number). Vista should reboot without any problems. In practice is this always true? Have Forum members experienced any issues with this? The user experiences a DISK failure. They install a new disk and then boot from the Acronis boot CD and rebuild the OS partition on the NEW disk (different Disk Signature and Drive Serial Number). In this case Vista should refuse to boot and should return an error message “winload.exe is missing or corrupt”. Have Forum members found that this is true? I quote from a technical paper on the subject.... If the above is accurate then it means that it is impossible to create a mirror system disk (or even a clone) and swap these out as needed. This means that in the event of disk failure Vista would have to be reinstalled on the new disk. In addition, users will not be able to create a mirror disk of the OS disk as an emergency boot disk in the event of system failure. This raises serious questions about the entire process of system imaging that we have all used for years with XP. All feedback and comments on this subject will be most appreciated. Thanks in advance.... T.
