Consider the following scenario. You install Windows Vista Service Pack 1 (SP1). At the time of the installation, you install a Serial ATA (SATA) controller driver other than the Microsoft Advanced Host Controller Interface (MSAHCI) driver. Then, after Windows Vista SP1 is installed, you update the existing SATA driver to the MSAHCI driver. However, when you restart the computer after you update the driver, you receive the following stop error message:

STOP 0×0000007B (parameter1, parameter2, parameter3, parameter4)
INACCESSIBLE_BOOT_DEVICE
