I had Win7 pre-installed. Edit: I'm new to BIOS modding. What does this exactly mean: "Original (non modified) same version bios MUST be flashed already !" How do I know if it's flashed or not? Edit 2: In other words, how do I flash it? Edit 3: I think I get it, flashing is somehow "installing". So I already have the same bios version flashed. Thanks, and sorry for trouble.
