Hey, I have solved the problem !!! It was due to RegTweaks.reg ... something in it makes it crash. On a solid unattended, without that reg all was fine, until I ran it, fully and the same problem happend. So I have added my full regtweaks.reg here, and I will test a lot but if anyone can spot anything that should not be here, or is not recommended, ANYTHING, please let me know: EDIT: so problem is actualy bootlogo.cmd I have.... Can it be that the OEMkrnl.exe from SP1 does not work with SP2 ? how to change/edit to make it work ?
