Trying to install SP1 for Windows 7 x64 and each time after it reboots the PC during installation the SP installation reverts itself due to a failure. Once I'm allowed to log in I get a windows saying Installation was not successful with an unspecified error and an error code: E_FAIL(0x80004005). The PC hasn't even been configured yet and I'm trying to do the installation from the factory image. I have tried installing it through Windows update and from the standalone installation file from the microsoft download center. Neither works and I get the same message.
