    Rufus may be an alternative for Windows user, anyway, had the same problem yesterday on Windows an on CloudReady Notebook, finally were able to write the stick when starting the recovery tool "as administrator" on the windows notebook. But it took me half the day to find out.

    Sorry your time got wasted - we just realized this info as well.

    Thanks for the suggestion of Rufus - many people seem to really like it, but we've never tried so far.

    Okay, Rufus does work, you just need to use the dd option and have the .zip extracted. (You need to select "All Files" in order to select the .bin) A great alternative due to this very annoying bug, also puts your computer less at risk with disabling UAC. :)

    Yeah I can agree Rufus is an excellent alternative it might take a while but it's worth it though.

    Hello,

    I haven't found a way to extract the image on my Chromebook, but once I have the image extracted, I'm able to write this to USB from a Chromebook.

    Windows side of things, Win32DiskImager worked fine, as did Rufus as long as it was in DD mode.

    David -

    Thanks for the thorough run down.

    As for the Chromebooks unzipping - you should be able to double-click the .zip in your downloads folder to "Mount" it - it'll show up like a USB drive would on the left hand column.

    You can then go into that "mounted" zip file and copy the raw .bin back to the downloads folder - then you can use the .bin file as normal with the utility.

    Correct Forrest, the Chromebook however complains of it being an incompatible file type. At first I thought this was due to being in the beta channel, but after trying on a stable channel Chromebook, I received the same issue.

    Keep in mind these are actual Chromebooks and not CloudReady devices. I have not tried to create a recovery drive with one of those.

    Try this:

    Find the shortcut for the Chromebook Recovery Utility.
    Right click and select run as Administrator
    Click on the gear icon and select Erase recovery media
    After the media i erased you can
    Click on the gear icon and select Use local image

    I have tried this two times now without any problems. Both 32-bit and 64-bit.
    It seems like it is important to Erase recovery media first sins update to Chrome v.50.

    Tried all of the above, and none worked. What fixed it for me was following the process laid out by blogger here: http://mychromehome.blogspot.com/2014/07/download-chromebook-recovery-image.html

    ...and reformatting my USB to use NTFS file system instead of FAT or FAT32.

    Don't know if it was just the file system that caused the error, so recovery image download and .bin file extraction may not be necessary

    Same problem on Mac as well.

    Simon -

    Your issue is unrelated to the issue Windows users were having - that bug got resolved by Google.

    Hey!

    I have tried on two different machines with two different USB sticks. Nothing.
    I have tried erasing the recovery media, as suggested somewhere above here. Nothing.
    It looks as if the Chromebook Recovery Utility is bricked. Or bricks.
    Very frustrating!
    I have been spending days on this. Not because I want CloudReady badly - for I do not! But because I only want to see what the problem is and whether it can be fixed. That is to say, whether a commoner like me can replace the OS on an old computer with this alternative from Neverware.
    But it seems impossible.
    If this CloudReady thing is for hardcore specialists, I reckon you should mention that on your every page. In big, bold, crimson letters.
    Thanks!

    Hi Mort -

    There are plenty of hangups that people run into in this process, but it isn't for experts. Lot's of people with little-to-no technical knowledge have been successful.

    I'd encourage you to port more detail about what computer(s) you're using, what USB stick brands and sizes you're using, and precisely what error messages you're getting in a new thread. People are very helpful around here, and I'll bet we could put our heads together to solve this issue you have

    Well, I am using a three-year-old i5 machine (128 GB SSD, 16 GB 1866 MHz CL9 DDR3 RAM) and a three-year-old netbook (AMD processor, 128 GB SSD, 4 GB DDR3 RAM). Windows on both. A 16 GB Toshiba USB 2.0 stick and an 8 GB stick from a mobile operator, respectively. All four work as intended. Not when it comes to creating that installer.
    No error messages, only the white windows showing no activity:
    - attempt at creating a recovery image: http://i.imgur.com/gfk9Nwh.jpg;
    - attempt at erasing the recovery media: http://i.imgur.com/JwTenma.png.
    I ran the program as administrator, yes.
    I followed all the instructions to the letter.
    Both said machines are still busy working towards creating that installer...

    interesting. Did you run Chrome the Browser as administrator? Definitely try relaunching the browser itself as admin if you haven't.

    Next question - did you try unzipping the file and THEN using the recovery utility? Any difference in behavior with that change would be menaingful data.

    Finally - try unzipping it and then using Win32DiskImager to write it to your USB - that may work better.

    I did, yes. Both the browser and the app were run like that.
    No, I did not unzip the file first. Looks like I will not go to sleep early tonight!

    Thank you for the tips!

    No success just unzipping and using the Chromebook Recovery Utility.
    Last chance: using Win32DiskImager.

    Unzipping the file, I get a file called "chromiumos_image.bin".
    Win32DiskImager does not see that. As if the file does not exist.
    When I try to open it with DAEMON Tools, I get this message:

    "Windows can't access this disc. The disc might be corrupt. Make sure that the disc uses a format that Windows recognizes. If the disc is unformatted, you need to format it before using it".

    It should be plenty possible to select the .bin using Win32DiskImager if you adjust during selection for all file types.

    However, http://rufus.akeo.ie/ that should work for you as well.

    I downloaded the .zip file again, using a different browser this time, I unzipped it, then I selected it in Win32DiskImager (all file types, indeed, as the only option).
    The installer seems to have finally been created (on the 16 GB drive)!
    I will test it tomorrow when I get to where my old computer is located.
    I do hope the reading and testing stage is done now!
