Guide to Adjusting BIOS Boot Order

[Gremlin]

You said you installed 2 x m.2 drives. I presume these were nvme-m2 drives. Were you able to confirm the system drives migrated successfully?

This situation is quite unique. Please turn off the TNAS, keep only two system disks, and then restart to check.If the problem persists, please contact online technical support for diagnosis.

I had several hour long chat with support that lead to nowhere. They wanted me to remove parts from below the motherboard having to dismantle it but I refused. Then they wanted me to schedule a full workday to try fix it with commands. I found that very unreasonable. Asked if resetting and re-installing TOS isn't faster and yes it is.

After reset it worked fine but after updating to TOS 7 it won't start again. This time I reset it with system drives being NvME from start. Will reset it tomorrow again and leave it with TOS 6 for now. Thought the TOS 7 update would work but it doesn't for me.

The update that I used was:
TOS_X642.0_Update_7.0.0747_1247_2606171225

Feels like it doesn't install the bootloader correctly.

I did reset the system again so now I'm back at original TOS 6 version (6.0.794), if I update with current TOS 7 then the system won't start at all so there is no way to remotely connect to it.

Last time when I had TOS 7 then I installed and updated to a newer TOS 7 version, and it worked fine on regular drives. That is until I migrated system over to NVMe drives, then it would not start. But at least the mobile app worked but not the web interface that said the BIOS boot order was wrong. Now that I had TOS 6 installed on NVMe from start and updated to TOS 7 (the update file is not the latest version), it would not even go that far that I could log into the NAS with the app.

Looked in the forum and it seems I'm not alone with this issue so I will have to wait until there is another TOS 7 update version available that fixes this problem.

BIOS version is MTWL0101.V07

A friend to me bought F4-425 Pro after me since Plus wasn't available but that came with TOS 7 from start. I would have bought that version as well but it wasn't available when I bought mine in April.
