Hi, Got three questions here, appreciate your help: Q1. If I do a clean install of OS using empty snapshot creation, (call this snapshot 2), is it true that if i do not install FDISR in snapshot 2 too, when reboot, i can never see the pre-boot screen; meaning i can't boot back to snapshot 1 unless i install FDISR in snapshot 2 together with the clean installation of OS? Q2. The latest version changes mention that the preboot hook has move to boot sector instead of MBR. If i install the old version first (which uses MBR) then upgrade to the latest version, will the pre-boot hook still be in the MBR or? or i need to uninstall completely the old version and install the full 3.2 version instead from leapfrog? (sorry, not much technical knowledge about MBR etc) Q3. I read that the ISR folder is hidden, and once change the folder view settings, I can see the ISR folder, but there is this folder name 0 which I was denied access to view. what is this folder and how to access the folder? Where is my snapshot stored? Many thanks!
