Drive Contains Image message when attempting to select thumb drive

Okay. I’m not a developer, so I’ve never used the DevTools console before. However, I didn’t see any errors when running Etcher.

Also, as I said previously, I’ve tried several different USB drives and all have the same issue, so it’s not the USB drive.

The link that you suggested that I look at is very similar to the issue that I’m having, however, I didn’t see a resolution.

For the source image, I’ve tried several, one that you can try is FreeDOS.img,

The path to my drive is “/dev/sdb”.

Thanks

Daryl
