It looks like my existing USB boot drive has failed. UnRaid not starting, tried the USB in my MAC and nothing shows up, the LED goes on and off for a second then nothing. Its a Sandisk 32MB very small version and is very hot now when I plug it in to my MAC for a minute or so. (Ordered a physically larger one in case heat was to blame for slim USB failure).

Is a step by step guide anywhere on here to show the correct way to replace, swap licence, restart the server. (Don't think I have a back up of any system files)

Will the array still be ok?

Thanks in advance.

Steve.
