X10DRH-C/i with Sandisk SATA SSD: RAID drives detected during CMOS boot and during deployment by Microsoft Deployment Tools. OS & drivers are installed to the RAID drive. On 1st boot, Windows gives error Inaccessible_Boot_Device. Running Windows repair gives the same error. Tried Intel RAID drivers from Intel and from SMC latest drivers. Also tried breaking the RAID. Unraided drives boot fine. Rebuilt the RAID. Same issue, same error.
You may try driver Intel PCH RAID Romley RSTE 4.2.0.1136 driver instead of the latest driver.
