Hello Just downloaded SP1 and installed it. After the reboot i got a error and the install was rolled back. I tryed again. First error was 0x800f0a13 That was an easy one. This has to do with missing the drivers for my ATI video card. Second Error was 0x800f0a12 This was also easy. just enable the automount function But than. If i start the service pack install i get the error message the windows 7 Service Pack Installation cannot proceed until your computer is restarted. Of course i reaboot my system. No difference. Then i check the regkeys that normaly trigger this error but ther where not responsable for it. SO PLEASE can ANYONE HELP ME Greetings Ronald
