Oh - if you dumped the contents that's a bit different - Win10 can only mount disc images, not base folders. You can try just running the installer, but it will likely complain about not finding the dat files or whatever from each disc.
If, when you dumped the contents, you put them in separate subfolders then that program I mentioned earlier (imgburn) can create iso files from a source folder. Otherwise you'd need to split them up etc.
If you already have the game installed elsewhere, you can just copy and paste the entire game folder and it'll run. If it won't fire up initially just delete or rename eqclient.ini and it'll generate a new one upon launch.
