I would like to install Chrome os ( vanilla ) on my old Toshiba laptop. I tried to burn the .img file to my USB. But My toshiba doesn't have any USB option in Startup Bios. Therefore, I tried to burn this .img to a DVD. But every time I tried with any burning software on Windows I get the message of " The img file is not supported ".

So do you have any idea how to burn this image file to a DVD ? Or do you have any other idea to install this Chrome OS on my laptop ?

How old is the laptop? Any recent machine should be able to boot from USB. Try inserting the USB stick and then check the boot order menu in the BIOS. – Karan Dec 21 '12 at 19:33

Simply change the file extension from IMG to ISO, don't worry nothing will happen to the file, if you're uncomfortable with this you can use ImgBurn to burn your file to DVD.

But I do know from Linux that you can't make a bootable CD ISO off a bootable USB, the reason for this is that USB images use syslinux as bootloader (which can only be installed on FAT32) and CD ISO's use isolinux as bootloader (isolinux won't install on anything but iso9660).

In order to get your ChromeOS to boot from a CD, you would actually have to make it a LiveCD, it doesn't come as a LiveCD nor is it offered as a LiveCD. That requires it to be put on a partition on the hard drive and then an image made of that partition so it can be converted to a LiveCD.

You changed the file extension or did you use ImgBurn? – James Young Dec 21 '12 at 15:07
I did change the file extension, it took me like 5 minutes to burn. When I restart my PC, it doesn't work. I even tried with different computer , but DVD is not working. – user181892 Dec 21 '12 at 15:08
I suggest you revert to the IMG file extension and try to burn it with ImgBurn or Ultra ISO – James Young Dec 21 '12 at 15:10
I already used both. The both seems working but somehow, but when I click on disk it says uncorrupted disk. It doesn't make it bootable. After when I select to boot from DVD it skip to HD. – user181892 Dec 21 '12 at 15:13

Have you tried unetbootin? It's the general go-to for writing ISO/etc. to USB.
