I'm trying to do a clean install on an AHCI SATA2 disk. Intel's instructions for its Rapid Storage Technology driver say to install the driver during the initial OS installation. So I put the drivers on a USB key and when I get to the point where Windows is asking which partition to install on, I click on the "Install drivers" button and then install the driver from the USB key. Then I can go no further after the driver is installed. Windows says "Error: 0x80300001. Windows is unable to install to the selected location". I have tried removing the USB key and refreshing but still the problem persists.
