I am using Paragon Partition Manager 10.0 personal edition on a new win7 64bit computer. I wanted to create a complete backup of the complete HDD (including MBR, C-System, D-Data) on an external HDD using supervisor rights. The backup wizzard required a reboot (saying "I need full access to the system") and then the machine would not boot again. I managed to restore the bootloader and MBR with the help of the original windows 7 installation disk in less than a minute but naturally I now hesitate to use paragon Partition Manager again. However it works fine on two other pc's under XP and VISTA resp. Any clues to make P.M. work safely under win7 64bit?
