The same thing happens with a new USB and fresh install of unraid. I guess that rules out likely USB stick issues and means I probably have an issues elsewhere in my system. I have been running unraid for almost a year and have restarted numerous times and never had this issue, so it seems unlikely to be a bios issue all the sudden causing problems. I guess a hardware failure elsewhere? I'll probably try swapping out hardware here in a bit. Ill start with the ram and see how it goes.
