When i want to install windows 7 64 bit version it has to reboot after Expanding files When it reboots it automaticly starts windows 7 while the installation wasn't complete yet (it still missed Installing Features, Installing Updates and the Completing Installation). It is a clean install and i also tried to install the 32 bit version but i had the same problem. I installed it on my brand new ocz vertex turbo After i have send the report to windows it i can click on more detailes about the problem so i did, and this is what i get: D:\Windows\System32\LogFiles\Srt\SrtTrail.txt X:\Windows\Temps\StartupRepair.etl D:\Windows\System32\LogFiles\Srt\DiskLayout.txt D:\Windows\System32\LogFiles\Srt\BcdInfo.txt D:\Windows\System32\LogFiles\Srt\Bootstat.txt D:\Windows\System32\LogFiles\Srt\Bootfailure.txt My dvd drive is the first boot device and my ssd is second (and last) I hope that this is all the information neccesary to solve the problem Thanks for all the help!
