tried 3 different usb sticks ( 1 new usb 3.0) I re-downloaded the img file from a different mirror. and tried re-flashing it. Interesting enough nas4Free boots off of the same stick that is failing? Ive attached a photo of the error. This machine was booting fine the hardware has stayed mostly the same though i did add a new sata card though i don't think that is the issue as n4f works OK its just not as finely polished as freenas. Ill pickup an new usb2 stick tomorrow and try again. Also i get the same error whether i extract the img file, or if i install to usb?
