I am getting a strange error while booting from a USB. I was able to boot from it a couple of hours back. I installed EOS on my disk, and everything was fine. Then I made some partition changes on my HDD. I do not know what it could have to do with booting from USB, but after that EOS does not boot from the USB anymore. While mounting a certain filesystem, it fails. Manjaro, Ubuntu, all are booting from USB.
Are you sure you made the changes on your HDD alone? Maybe you somehow messed up the USB drive. If it doesn’t load, the first thing I would do, is to simply write the image to the USB again.
But still I wanted to be sure. I installed Easy2Boot on another USB and copied Manjaro, EOS, and Ubuntu ISOs. Only EOS did not boot. The other two had no problem.
