Hello, am trying to install win7 (no beta) on Qosmio F30-140.I start the installation and the files are copying to the hdd. Then the computer starts again for the installation. But every start is ending in a blue screen with error: stop 0x0000007E.

BSOD usually indicates either bad drivers or bad RAM. Since you're just starting the install, it is unlikely to be a driver at this point. That leaves RAM.
Check your BIOS. Does it see all your memory?
Try searching Microsoft.com (or google) for stop 0x0000007E and Windows 7. There are multiple results for that search, most of which mention Win XP and some for Vista.
