How to convert from .RAR to .ISO file? (For Lenovo OKR7.0 Engineering)

Hi all;
Just downloaded the OKR 7.0 Engineering edition from FileFactory.
Source: Lenovo OneKey Recovery 7 Engineering DVD - Software Chat - nsane.forums

However, the file format is in .rar
How can i convert it to .iso format? This is because i want to burn the file to a DVD.

One side question. Have anyone owned a Lenovo Y580 that comes pre-installed with Windows 8 but then downgrade it to Windows 7 using UEFI and managed to use Lenovo OKR 7.0 Engineering edition?

Please help.....

Have you tried extracting it with WinRAR or 7zip?

I'm sure the ISO is inside the compressed container.

Hi - unfortunately, the entire file is .RAR The file is not being zipped or something like that.
Please refer to the printscreen of the file. Hence, how can i convert this file to .iso ? The instruction per the website below states that we need to burn the file into DVD and boot from the DVD itself. Hence, i do not know whether we can burn into the DVD using .RAR format? From what i read, only .ISO format can be burn into DVD. Please help.

A rar file is also a compressed or "zipped" file exactly like a zip file. WinRAR, WinZIP, 7Zip and other compression apps can open the rar packets. The ISO file is in the packet and needs to be extracted.

Back in the win 7 forums again, hello. Short note, if you download a zip, rar, exe, interpret this as a 'file' download - you can pop open the rar with a tool like winrar (usually uninstall after - just to keep things simple) to iso, this is your 'image' file, and so you need software to take a 'snapshot' of the cd contents. Google gizmo tools - this will also you to create an your iso file of your cd, once you have loaded it with content, and also virtualize your cd drive to load up your images.

OK. Please correct me if i am wrong here. All i need to do is to download WinRAR. Then, unzip the .RAR file using WinRAR and look for the ISO image file. Thereafter, i just need to burn the ISO imahe file straight to the DVD.
Is this correct? Thanks for your help.

Hi all; It appears i am stuck in the mud... Need some simple step by step instruction on how to burn .RAR file into DVD.
Please refer to the printscreen below. I have extracted this Lenovo OKR7 Engineering Edition DVD.rar into the following folder using .winrar.
-2013-06-16-11_49_02-g__y580_software_okr7.0-engineering.png

Now, i need to burn this to a DVD to create a bootable DVD.

So, using Winrar, i actually extracted everything as shown in the folder below.
-2013-06-16-11_50_38-g__y580_software_okr7.0-engineering_lenovo-okr-7-engineering-edition-dvd_okr.png

But then, do i burn all these files into the DVD? Seeking high and low, i tried looking for the iso file but cannot find any.

I try looking for the .iso format but the only one that i can find is this.
-2013-06-16-11_52_45-g__y580_software_okr7.0-engineering_lenovo-okr-7-engineering-edition-dvd.png

I burned the above file .iso into DVD and then try to boot from it. But nothing happens. Can anyone please help? After checking the DVD, it shows what i burn is winrar archive....
