Hi guys need some help here. I have downloaded the Retail DVD of Snow Leopard(DMG).

Now, I want to burn it into a DVD DL. But I dont have access to a Mac. How do I do it on a PC(Running Wndows 7 Ultimate x64)?

Based on some search that I did on google I found that:
1) Rename the .dmg to .iso and burn it using nero works
2) Have to use software like transmac

I am unsure which is the correct way. I need the DVD to be bootable as I'm going to install Mac on my other HDD. Please suggest a way to do it.. Thanks....

Ive never had luck with either of those to methods(they mad me make coasters lol). I did however use poweriso which has a tool to convert dmg to iso, it works perfectly, after its converted burn the iso with imgburn.

Just use PowerISO.
