Hi all, with carefully reading the posts and following tutorials, i made a perfect setup to handle my PC needs. partition 1 : XP/Windows 7 in two snapshots i boot as needed to change windows os Paritition 2: Data to share and backup with syncbackpro Partition(s) ahead : Ubuntu 10.4 External USB drive : Ceedo/PortableApps to keep my system clean and keep programs settings through install/reinstall/format.... Paragon backup to handle partition backup. Bullet proof !!!! I have still a question : I did the use the Bootsect_x86.exe file prior to install FD-ISR on the windows 7 snapshot. What about its use if i need to 1) reinstall from partition image (i thnks it's useless but..) 2) reinstall from archive of FD-ISR In other words, once Windows 7 snapshot completed, in which situation may i use Bootsect_x86.exe again? Thanks for input. Laurent.
