@Cr0nJ0b I doens't POST because you configured the drives as either primary or bootable. At least, that was the problem i had with TestDisk and my RAID 5 array... Still don't have my data back by the way, but did discover the POST-errors. I just made all the drives non-raid again and started again. You can go to the Intel screen with CTRL-I before EFI does more, so you can just revert back to that state.
