SafeDisk V2.9 ISO Question

[SeatoSky]

Hi all,

Using latest Alcohol120% version and my CDRW I can create a .mds image and mount it no problem, game runs fine without CD in. I can also make an ISO image to HardDrive file no problem.
I used FireBurner to burn the ISO image, created in Alcohol120%, to CD.
When I boot the backup CD it asks if I want to install the game, exit, etc. It does not ask if I want to play it, as it is installed on the Hard Drive from the original, which has been updated-patched twice now. I obviously do not want to install it again, I want to use it instead of my original.
Also, if I try to start the game, from the desktop icon created on the original install, with the backup CD it loads to a splashscreen then drops to the desktop after a bit. I am confused as to why it seems to have backed up ok, ie: wants to install, but will not work to pass CD check.
I am clearly a newb at all this and would appreciate any advice.
Thanks Seato.
