i have vista64 loaded on a new hard drive and downloaded win7 64 and got this error: "You can’t upgrade 64-bit Windows to a 32-bit version of Windows". i double checked my vista dvd and it only has 64 on it. under system information it reads that it's a 64 build. even downloaded the 32 win7 version and got the same error. even had a friend burn it on a flash drive. still the same error. why is it reading that i have a 32 os?
any clues?
It's saying you already have 64bit windows Vista and that it can't upgrade that to 32 bit windows 7. You need to download Windows 7 x64 and install that if you want to do an upgrade. Alternatively you could do a clean install of 32bit on a different partition/drive.
Vista 64 can not be 'upgraded[' to windows 7. Download Windows 7 RC and make a proper install disk and install Windows 7 RC as a stand alone installation. The installation of of Windows 7 RC has nothing to do with a current installation of Vista 64.
Use the download link and burn a proper install disk of windows 7 RC. Boot to the disk and install it as a stand alone OS system with nothing to do with an existing Vista 64 installation. Installing it on the second spare HD would be the easy way. A boot menu will appear when the system is powered on asking which OS you want to boot to, Windows 7 or Vista 64.
If you have Nero installed, that program will burn an install disk after downloading the Windows 7 RC installation. Other DVD burning software will also work if installed on your system.
It is not recommended to "upgrade" any operating system to Windows 7RC. When installing any operating system it is always recommended to perform a CLEAN install on either a seperate partition or a seperate hard drive.
