I understand you had problems with Intel® Rapid Storage after updating BIOS on your system.
The problem seems to be a registry issue and would not be fixed until you re install the operating system.
This happened because the BIOS changed SATA modes and the registry of your operating system was modified.
I am using windows 8.1/64. recently i have a problem with intel RST, the error message were "intel RTS not running". I had tried too many options/methods unfortunately unsuccessful. I had decided to uninstall for a while hoping that i can reinstall it easily but again i am having a hard time to reintall it. Kindly help me if there's any way to reinstall intel RST.
I am sorry to hear you have this problem with Intel® Rapid Storage.
If this is a registry problem, you may need to fix the registry by running System Restore for your operating system.
Or the last resort would be re-installing the operating system from scratch.
