I am attempting to install Win 7 64 Pro from scratch. I had to replace the hard drive, so I have nothing to "repair".
I downloaded and burned the image given in links here and was able to get to the Command Prompt to get my date files off the D drive. Tried to install using the same burned disk and it seems to start ok but I get an error message, "Windows cannot install required files. The files may be corrupt or missing. <yada yada yada>".
Also, now both the old secondary disk and the new primary disk are showing, but for reasons that are beyond me the computer has chosen to rename the old date drive (was D drive) to C drive, and assigned D drive to the new disk. Not that this is a huge deal, but technically not what I want.
Anyway, I am currently re-downloading the image file to see if that helps. Is there something I'm missing and should be doing differently?
