Hello everyone. Yesterday i tried to install Windows 7 64 bit on my computer, parameters were good and everything. I have read threds about installing it without cd/dvd so i tried that option. Everything was going ok till this infamous black screen occured. I tried many options found on the internet but nothing really helped. And now im stuck with error about that system cant complete installation and it keeps resetting. I'm aware of that i wont finish installation without Windows on cd. But my question is, can I somehow restore computer to the Point before installation started? I cant even access desktop im just stuck on that installation failure everytime it restarts, same goes for safe mode.
