You cannot use ISO directly in the same way as Windows 8 recovery (which by the way use 'ram-loading')
Instead we must practice 'frugal solution' to software like kaspersky (and to a lot of other software as well)
Test guidelines and solution given HERE
Note1: Kaspersky is 'sensitive' and seems to behave 'unfriendly' sometimes, but be patient and redo your build to make it work alright
Note2: I'm heavily occupied for several months with renovating my home residence
Above means I may participate only fragmentary in this forum for a long time ahead
