To the best of the this computer user's knowleage, this computer originaly has Vista (german version) installed, than it has Vista (english version) with loader (?) When I start with it, I run VOATKToolsv2.5_Stand_Alone, than remove, wipe and re-create all partitions (bhw, wiper says that it can not erase some blocks). Than I install Win7, flash original BIOS 1.10 and make RW report. Something is looking wrong so far?
