Hello Friends! I want to install Windows 7 on 256 MB RAM PC. I found this following information, I wanted to ask, 77073D7801 ---> These are Even Digits Total 10 But, E90400000 ---> This is Odd Digits Total 9 My appeal to all the very knowledgeable people here. When I find and replace from Notepad++. It says, "There are odd digits. The data will be truncated!" Is this the correct HEX string or there should be another 0 in the E90400000 Your input would be highly appreciated. Thanks!
