I purchased a CyberPower computer. It came today and I set it up. I got it to start running, but accidently typed in the wrong serial key for the Windows 7 Home Premium 64-bit. I didn't know what to do so I put in the recovery disk and reinstalled windows. When I reinstalled windows, it installed Windows 7 Home Premium 32-bit. I typed in the right serial this time though so it was good in that way, BUT NOW IM STUCK WITH 32-BIT!!! I tried reinstalling it again thinking it might install Windows 7 Home Premium 64-bit, but it just reinstalled the 32-bit version. What do I do? How can I get my computer to go back to Windows 7 Home Premium 64-bit version.
You cannot upgrade from a 32 bit OS to a 64 bit OS.
You will need to do a clean install of 64 bit.
Apparently cyberpower supplied you with a 32 bit recovery disk, not the 64 bit one. Go to them and get the proper one.
In the mean time, if you have a 64 bit windows upgrade dvd, you can proceed.
Boot from the dvd, and do a clean install, but do not enter your product code.
That gives you a valid windows 64 that is good for 30 days.
Then running windows 64 , insert the dvd, and tell it to do an upgrade.
At the end, enter your product code to activate.
The oem product code is the same for 32 bit or 64 bit.
