To boot an iMac from USB the installer files need to be placed on it in a certain way, using the Terminal createinstallmedia command. Doing that on a Windows machine would mean you have to follow @Feartech 's guide instead, but without OpenCore in the hidden EFI partition. Maybe Legacy would work (?):

The problem on a real Mac is the EFI partition as it doesn't use this, so has to find what it needs in the main partition. Hence the trickiness of using Windows.

What or where did you get th ISO image from?

The only approved way (for this community) is to boot into the SL install DVD. Hopefully a genuine retail disk made by Apple, not burned to a DVD by some Ebay seller trying to make buck by illegally copying software.
