You can also purchase software like Nero or Sonic Record Now to burn Blu-ray discs or you can use free open source Blue-ray burning software. That’s why I’ve come up with a list of free apps you can download to burn Blu-ray discs. I’m sure there will be a lot more freeware apps soon, but here’s what I could find so far:
burnaware 
BurnAware is a very simple and easy to use CD/DVD/Blu-ray disc burning app. You can use it to create data backups, audio CDs and to create or burn ISO image files. The free version does not support disc copying or bootable discs.
cdburnerxp
Another good freeware app to burn CDs, DVDs, and Blu-ray discs. Like BurnAware, you can create and burn ISO images. However, with this software you can create bootable discs and convert BIN/NRG files to ISO.
starburn 
StarBurn from Rocket Division is a nice full-featured CD/DVD/Blu-ray burning app. It has a nice GUI interface that splits your burning options into audio, video, and data. You can burn images and build ISO images also. Unique features include the ability to erase a disc and to compress audio.
4. ImgBurn
imgburn 
ImgBurn has been one of my favorite CD/DVD burning apps for a long time and now it also supports Blu-ray discs, which makes it even better! It has a bunch of other features that make it popular, including supporting the latest drives, the ability to batch create images, support for a wide range of image file formats, and lots more.
express burn[4]
Express Burn uses a propreitary optimization system and claims to be the fastest CD/DVD burning software. Not sure if that’s true or not! Has all the features mentioned earlier, plus some extra like recording video files to PAL or NTSC format and choice of widescreen or standard format for DVD authoring.
finalburner
Finally, FinalBurner is the last free Blu-ray supporting disc burning software out there. You can use it to create a data cd, audio cd, and video cd.
