Samsung Galaxy S III i9300 Boot Loop, No Recovery, after Cyanogenmod Installer
If you have access to the Download mode, then nothing is lost.

I suggest you not to repartition the device first, just try to get a standard ROM flashing done. Based on my experience Odin usually fails because of driver issues (I had plenty of problems using Win 8.1 x64, while just doing the exact same procedure on Win7 worked well)

Also if you had USB debugging enabled, you might catch what's the problem during the startup/bootloop using logcat. With some luck you might push the missing files to your device as well.
