Hello! I installed Win7 OEM, 64bit on Lenovo y510p - turns out the OEM or Daz activation didn't work and it was unactivated and due to expire in 3 days. I tried to use this "clearmarker" and "setmarker" thing on DOS usb stick, but I may used wrong markers or something, now other marker images don't seem to work and Windows7 refuses to boot up. Wtf to do :/ ?
if you format partitions in GPT then DAZ activation will not work. DAZ Loader functions only in MBR mode. i think your OS is GPT based formated. so....reformat your hard disk in MBR (Master Boot Record) mode and install windows and apply DAZ Activation.
