Now I understand how the mutliboot cd/dvd work in principle for install windows, but do have a few questions 1) how would they work for doing a repair install of windows, ie during the setup it fine windows and you select "R" for repair? 2) how do they work / would they work for when you need to run the system file checker (sfc /scannow) The reason why im askings, is because right now we have 5 cds at work when we works on customers machines, home, home sp1, home sp2, pro sp1, pro sp2 and would like to condence this down to 1 or 2 cds, only if they 2 questions above work fine thanks
