I can not record a ISO image in my GH22N550 - LG GH22NS50 22X DVDRW SATA Drive OEM DVD-RAM Burner

Besides from a disc drive and a blank disc for burning or copying iso, you also need a program for doing the burning process. There are 2 methods for your reference whether you are a Mac user or Windows user.

Copy ISO to DVD with Disk Utility:
1. Insert a writable blank disc into the disc recorder drive.
2. Launch Disk Utility. Click the "File" from Disk Utility menu and then select "Open Disk Image" option.
3. Browse source ISO image file and then click "Open" to add source ISO image file into Disk Utility.
4. Select ISO image file from the left panel and then click the "Burn" icon to start burning disc image to disc on Mac.
Note: Since Disk Utility is developed by Apple, then this method is for Mac users. If you are a Windows user, you can also check the next method.

Copy ISO to DVD with Leawo Blu-ray Copy
1. Insert a blank writable disc into the disc recorder drive. Drag and drop your ISO image file onto Leawo Blu-ray Copy.
2. On the popup "Add iso file" interface, set "Copy to" and "Disc Label" options.
3. Click the "Burn" button on the "Add iso file" interface to start copying ISO image file to blank disc immediately.

Try using this software, Image Burn. It works for me every time. I gave up on all others. This program will burn ISO's to ISO's, it will burn ISO's to Boot Disks, it will make files into ISO's, it does it all.

Also, just to clear up the term, when you burn a ISO you are generally trying to make a bootable disk, you are not actually burning the ISO, but expanding and burning the files onto a CD or DVD that you will use to install something on another computer.
