There are many ways to make a working bootable USB Mac osx installer.
I'll start with the 2 Windows Tut.
Downloads: Download PowerISO.exe from here.
Installing: Install poweriso, it's crack
Bootabling : Click on Open and select your DMG or ISO file then click on tools ---> Create a bootable USB
Device: Select your device to install it on
Start: Click on Start and wait until it finishes (for 4.5 GB it takes about 3/5 minutes)
Finish!: Congratulations! Now you have a bootable USB media.
If it won't work by selecting F12 at boot prompt, modify the BIOS to boot the USB before everything.
ONLY IF ABOVE WON'T WORK
File -------> Open ------> Select your dmg/iso file
Right Click on USB device ------> Format with disk image and select your disk image
Start format and wait
You now should have your Mac OSX bootable USB.
Hope it helps.
