Dogsnake :
Is this a new system?Are you installing on a new HD? Are you trying to upgrade from some previous version? List your hardware configuration. What version type of Win7 are you using (OEM, Retail, Digital download,CD, downloaded image, etc.). Is this a legit. copy that you bought and are you using a valid, not used before product key? Perhaps any other information would be helpful also.
First, i'm using image downloaded from this torrent http://thepiratebay.se/torrent/7049713/Windows_7_Ultimate_32_64-bit_RemoveWAT_Included_ , i made bootable usb using power ISO, i have used that image on many computers by now and i have never had this problem, computer configuration is older (everything is listed in attached photo) new power supply is in (550 W) and new graphic card (XFX amd radeon 240) there isn't supposed to be any OS installed on the hard drive since that is new too, (toshiba 500 GB) i was, however told that motherboard have been reseted (power supply and battery removed) so i'm guessing that there is sth to do in BIOS but i cant find what is blocking installation. (this is my brothers computer and a few people tried fixing it beafore it came to me)
EDIT: i cant upload photo here, any idea how i can send it to you so i dont have to type everything?
EDIT:
anyway:
