I have a Samsung RV409 (search it online). I tried installing Windows 7 in AHCI, but it keeps freezing during the Windows logo loading and doesn’t start properly. It works fine when switching to IDE mode. In IDE, my 120GB SSD only runs at 110MB per second, which is slow. The weird part is it takes nearly two minutes to reach the desktop after turning on the power. I’ve decided to install Ubuntu instead, but it still doesn’t boot in AHCI and only loads about half a minute. I’m okay with that since I mainly use it for mobile tasks like coding. However, I keep wondering if there’s a way to get Windows to run in AHCI mode, which would make the SSD speed much better. To be honest, this machine couldn’t even run Windows 10 because the Broadcom Wi-Fi adapter isn’t compatible—installing the OS won’t work. Thanks for any advice!

Consider changing to AHCI mode and starting in Safe Mode. This approach helps Windows boot properly when you switch the BIOS from AHCI to RAID, and it’s worth checking if doing the same with IDE to AHCI yields similar results.

It doesn't make sense because the safe mode stays unresponsive.

AHCI needs a different driver because the boot sequences differ from IDE. Stick to IDE, save your files, and reinstall the OS using AHCI mode.
