linux_inside,
Stupid Question: What burning program are you using, the only infomation you have given us is that it is in WinRAR, and as far as I know it is not a burning program, it is an archiving program
If you are using nero Start smart, you just go to the copy and backup utility, find the file (ISO) you wish to burn, click burn and hey prsto you have yourself a functional Linux CD...
Here is A FREE Iso Burning Tool called Iso recorder power toy you can D/L it from the Link below

Here is how to burn the ISO
Steps to create a CD if you have installed ISO Recorder Power Toy:
1. Download the ISO CD image to a folder on your computer.
2. Insert a blank CD in your CD-RW drive.
3. Start Windows Explorer.
4. Locate the ISO file, right-click the file name, and then click Copy image to CD to open the ISO Recorder Wizard.
5. Follow the steps in the wizard to write the image to the CD.
Another alternate method:
1. You can also right-click your CD-R drive and choose Copy Image to CD.
2. In the new window browse to the ISO file and click Next.
