Can't create restore image

Not sure what I’m missing here, the instructions are clear but vague. I download the system image, extract, run the command and nothing happens. Tried on windows and linux.

Anyone have any idea what I’m missing?

Do you see your flash drive in your system?

What output do you see when running the CreateUSBKey.sh script under Linux?

Do you run it as user root?

sudo CreateUSBKey.sh

Do you see the FastOS Logo? This is what you should see (the device path /dev/sda might differ depending on your system).

$ sudo ./CreateUSBKey.sh

Depending on the speed of your flash drive it may take some time (minutes) before the success message is printed.

“Nothing happens” - I would at least expect an error message from the script before doing nothing. 😉
