Failing that, I assume you're plugging the SSD into the integrated SATA socket on the motherboard. It may be worthwhile checking the motherboard manufacturer's website to see if there's any firmware upgrades for the board that may fix this issue ? It may be a known fault ? Be very careful upgrading the firmware - read all the documentation first so you understand the risks.
Thank you for your replies! Yesterday I've updated my FW to the newest, so it doesn't writing this error message for me anymore, but it's trying to boot now, and then restarts. I've plugged my SSD into both (gray) SATA 6GB/s ports, but nothing changed. In boot prio, tried SSD as first and second too - nothing happened. Now I'm trying to reinstall windows again as maybe it could fix my problem.
