According to this screenshot you posted, the system is reporting less
than 512MB of ram, which is causing the failure. You say it has 4GB
though? What does the BIOS report? Also, did you test this on 9.0 or
9.1-RC1?

I test on 9.0 and 9.1 beta , but not RC1 and i have the same result. Must to have AHCI enabled by default in bios?

@Mr.Bean thank you for suggestion
