Loading a Recovery Image for the Cr-48 on Windows

Posted on 02. Feb, 2011 by in Chrome OS, Tutorials

flattr this!

usbrecoveryI recently had a run a recovery of my Cr-48, and to my surprise the Google support pages don’t offer a how-to for Windows, only Mac and Linux. If you’ve ever loaded a bootable USB image you’re probably familiar with this process, but here are the steps for those who have not done this before.

You’ll need a USB drive that is 4GB or larger.

Part 1: Writing the Image to a USB Drive

You will then need to download the image: https://dl.google.com/dl/chromeos/recovery/latest_mario_beta_channel. Once the file has downloaded; extract the .bin file

You will need to rename the file to an .img extension. Here is an example:

ChromeOS_0.9.128.8_x86-Mario_beta-channel_RECOVERY_MP.bin
to
ChromeOS_0.9.128.8_x86-Mario_beta-channel_RECOVERY_MP.img

Download Image Writer for Windows from here.

Insert a 4GB USB or larger memory stick into your Windows machine. (Note: a commenter has said that 2GB is enough)

Once downloaded, extract and run the win32diskimager.exe tool on your windows machine.

Inside Win32 Disk Imager; select the image of the file to browse to find: ChromeOS_0.9.128.8_x86-mario_beta-channel_RECOVERY_MP.img

Select Device (using drop down to find USB drive letter)

IMPORTANT: Make sure you’re using the drive letter for the USB stick or you risk corrupting other drives on your system.
Choose “Write” (which will write data in image file to the USB Stick)

Select Yes when prompted

Writing to the drive should take less then 5 minutes

Part 2: Running the Recovery Image for Chrome OS

You will need to be in developer mode for this. Instructions are here. When the “Chrome OS is missing or damaged” screen appears, insert the USB Flash drive you created into the USB port on the right side of your notebook.

Wait for the notebook to boot up from the Flash drive.

Follow the instructions that appear on the screen.

On successful reinstall, the system will automatically restart.

Remove the USB Flash drive from your notebook. You may need to hit CRTL-D at the recovery screen because you are still in developer mode.

    Just an FYI, the link for Image Writer for Windows is broken already. (https://launchpad.net/win32-image-write) If you add an r to the end, it works fine through. https://launchpad.net/win32-image-writer

    Hope this helps! :)

    I did this successfully based on the dialogue on the screen :) got to the part where it said recovery succeeded and system will reboot in 2 minutes.
    When it rebooted I was right back at the error/recovery screen again :(
    any tips on how to proceed from here? do i need to be in Dev mode to do this? should I try that?
