Hi After upgrading and everything is good i can't backup my C drive due to this error attached. As you can see my backup drive is 1Tb and has over 400GB left and my C drive is only 79.15gb. i tried another drive and got the same issue any idea? I can backup using different program but i also want MS image copy for additional safety Thanks
Finally fixed I used guru partition to open the drive and i could see windows 8.1 created a new partition (500Mb) recovery when i already had one(also 500mb). so i delete old partition and launched the shadow copy and it worked. so to recap you should only have efi---200mb Msr--128mb Recovery--500mb Windows any extra partitions if you want
