Until recently, I was running 32bit Vista. Last week, I installed 32bit Windows 7 (7100 build).
That worked fine but then I decided I'd like to install 64bit Windows 7. I don't use torrents so I made an installation disk from 17 Rapidshare files provided on another (reputable) forum. This was the 7127 build of Windows 7 x64. When I inserted the disk and clicked 'run', I got an error message. A similar message came up when I went into the folders on the DVD drive and clicked 'setup.exe'. The two messages are attached.
I went into BIOS thinking I might be able to boot from DVD drive but, even with DVD selected as first boot option, I got the usual choice of Vista or Windows 7 (I haven't deleted Vista yet).
What am I doing wrong? Many thanks.
