hi Microsoft forum Normally I've no problem in create a system backup image and restore it back to formal state. However, after a while say a few weeks or a few months when I feel like to restore windows again, it fails. I don't know what happens here, the image restore tool simply says something is wrong during the process. Nevertheless , Windows 8.1 does not fail to boot and work normally, this only happens when I try to restore windows instead of running setup and install all drivers all over again from the install disc. Please help, I hate to see that system restore image that I paid for goes wasted. my questions are: 1. what kind of information it tries to look for when restoring system image? I'm very sure my image files are well kept safely and separately on two different hard drives each time I backup my system. (To verify that, I run windows setup and install from scratch then restore system image) 2. Is this something to do with the 350MB system reserved partition that is invisible normally? I could assign it to a drive letter I want in disk management but still windows sees it as empty when it's actually used 250MB out of 350MB currently. 3. how do I help myself in this situation in case someone made funny things to my boot partition (system reserved partition) ?
