Hi Nikolay, on balenaEtcher, you can open a console with `Ctrl + Shift + I ` and that might give you more information about what is going on in case there is an error. Check it out, and if you cannot make anything of it, let us know, will try to help out Good luck! ---

I don’t see anything wrong. Is that where it stops working? at 14%, it says **flash failed** and nothing happens afterwards? You mentioned that after that, you opened the SD File System in Windows, and only so the boot partition. Actually windows does not recognize all types of partitions, so, if you don’t see them there it doesn’t mean they don’t exist. Have you tried the SD card in your end-device? ---

Hey @Mochipet, I tried downloading and flashing the same octopi-buster-lite-0.17.0.zip file on my Win10 x64 PC and didn’t run into any issues with validation. You said you tried multiple SD cards and multiple files? Can you provide an example of another image file you tried flashing with Etcher? Did it fail during validation as well? I saw this warning on [octoprint.org](http://octoprint.org) so at first I suspected an issue with the image, but if you are seeing the same behaviour with other images then we may be looking at a larger issue. > There have been some reports regarding current revisions of the Raspberry Pi 4 1/2/4 GB refusing to boot with the stable OctoPi 0.17.0 image. If that affects you, please try the OctoPi 0.18.0 release candidate. Do you have any luck with the SD card in your end-device, even though the validation failed? Also some additional information for you once we get your Etcher install working. We actually have a barebones project for running Octoprint on balena if that is of interest to you: > **[GitHub - balena-io-experimental/balena-octoprint: Remotely control your...](https://github.com/balena-io-experimental/balena-octoprint)** > > Remotely control your 3d-printer with Octoprint and balena! - GitHub - balena-io-experimental/balena-octoprint: Remotely control your 3d-printer with Octoprint and balena!

Hi folks - Can you mention the version of etcher that you are using? Please ensure it’s 1.5.113 - being on the latest helps us easily recreate issues - Once you download the image from Octopi, can you run a md5-sum and check if the resulting value matches with the one mentioned here - [https://octoprint.org/download/](https://octoprint.org/download/) . Make sure that you run the md5-sum command on the zip, and not the img itself. This will ensure that the file you have downloaded is complete. - Lastly - have you tried this on any other laptop/PC? Do you see the same result? ---

This is a known issue on Windows for disk images containing fat or ntfs partitions. Please check [https://github.com/balena-io/etcher/issues/3197](https://github.com/balena-io/etcher/issues/3197) and this thread [Checksums do not match](https://forums.balena.io/t/checksums-do-not-match/36537/82) TO summarize, the SD cards were most probably flashed fine but the verification fails because Windows is creating folders / files on fat partitions before the verification.
