F4-423. The BIOS did not need updating.
I installed a 512GB NVMe to install the latest TOS. All went well, I can boot and I see TOS-7. It updated once more.
I have the NVMe set as boot option #2.
When I add drives to the NAS I get this:

I tried making Boot Option #1 as the NVMe but that didn't work.
If I remove the hard drives, then I can boot without any issues.
How can I fix this?
The hard drives were in this NAS before, I did not format them. The NVMe is brand new, and as I said it works just fine. If I insert the hard drive AFTER I boot from the NVMe, the system sees the hard drives and I can mount them, but if I reboot, I get that error message.
Please help.
