Machine independent restoration (M.I.R.)
Machine independent restoration (M.I.R.)
Until now, you were only able to restore a system partition onto a computer having hardware identical to the source
computer. The same goes for the restoration of clones. The most frequent application scenarios have therefore been
limited to the creation of images and restoration of these on the same computers
O&O DiskImage now offers you the option of restoring an image, even the system partition, onto a computer with different
hardware using the M.I.R. function(Machine Independent Restoration). You can also clone a computer with different
hardware.
Enable M.I.R. if you've made changes to the hardware after imaging and these changes affect the functionality of the
Windows operating system being started. M.I.R. is also necessary if you want to transfer an already existing computer
configuration onto a new computer.
M.I.R. can therefore be used or enabled in the following cases:
• Restoration of an image onto a computer with different hardware or cloning/duplication of a computer.
• With the help of a bootable disk, M.I.R. can be used for exchanging damaged or malfunctioning drivers of an
existing system.
• Migration of physical computers onto virtual machines or virtual machines on physical computers.
Note: When duplicating a source system, i.e. duplicating installed Microsoft Windows operating system versions
and programs, we recommend changing the computer name and SID to avoid future problems when using the configured
computer within the network.
Restrictions when restoring on different hardware
Under certain circumstances, it's possible that the restored or duplicated system does not start or is malfunctioning.
The following constellations may lead to malfunctions:
• No hard disk was selected as target, only part of a hard disk (partition/volume/empty area).
• While creating the layout on the target, "delete layout" was not selected. This option makes it possible to create
partitions/volumes on a different Offset.
• You did not select a hard disk as source but rather individual partitions/volumes and are missing the partitions/volumes
containing the needed boot information.
• You are trying to boot from a hard disk connected to controllers that were not initialized by Windows at the time
of booting, e.g. booting from a hard disk connected to the computer via a USB controller (not a USB stick).
Note: If error messages appear during booting, you will get instructions on how to proceed in chapter Assistance
when error messages occur during booting.
Note: To make sure a restored system or clone is bootable, it's important to create an image of the entire system
hard disk and then restore/clone it completely.
Restoring with M.I.R. automatically
M.I.R. of O&O DiskImage is available to you when restoring system partitions from an image or when cloning. Meant is
the direct selection of the system partition or the indirect selection, e.g. the entire disk including the system partition.
