Perhaps the image was corrupt - have you validated it ?
There are thousands of checksums along the file, and as soon as Acronis gets to an invalid checksum it will not continue.
Acronis make heavy use of most of your RAM - far more than most applications.
If your RAM has any imperfection that can cause an un-bootable image.
Do you have alternative images you can attempt to restore ?
Have you EVER had a successful restoration - some Acronis users only try it when they need it,
and just possibly they may find the Boot-CD linux type drivers are not compatible with their hardware.
Presumably your dual boot machine has some sort of boot manager which may be in its own partition or the MBR.
Perhaps it is no longer compatible with the configuration of the Office partition (C:\ ??) you are trying to restore.
If you do the wrong things to the MBR it is possible you will not be able to Boot from any of your systems.
I use Acronis 11 and have various contingency plans prepared,
so it knows not to mess with me ! ! !
There are many experts with far more knowledge than I athttp://forum.acronis.com/
They can advise you, and may be able to supply an alternative Boot-CD for better hardware compatibility if appropriate.
