Windows 7: Dumb Question: Can I install x64 on a 32 bit machine?

02 Aug 2009   #11

Windows 7 RTM

Scratch what I last said. there is an Iso file amongst the other files/folders. Its 3 gb in size so that sounds about right.
Now I need to make it bootable.

The Iso is bootable, just burn to disk, that's all

Windows 7 Pro X64 SP1

According to, the T7100 is a 64 bit CPU.

Why do you wish to install Win7 X64 on a laptop? The main reason most people would run X64 is to address more than 4GB of RAM.

If you have an .iso, it's usually an image of a bootable DVD.

A suggestion: make sure that you have drivers for key susbsytems in the nootebook. (LAN drivers, wired and/or wireless are particularly useful if you don't have ready access to another networked PC.) Vista drivers can often be used if no Win7 ones are available. The Win7 installer may contain all the drivers you'd need, but it's not a good idea to count on that.

I agree with bobkn....WHY do you want to install x64??
Have run both 64 and 32 on a number of computers, and unless you are doing heavy duty work, it is almost impossible to tell the difference.
What ever turns you on....but for most laptop users ( unless you have more then 6+gb of ram) it just does not make a difference.

A 64-bit processor does not necessarily make a 64-bit machine. Run the test GRC SecurAble. Test for availability of all drivers. Would be easier to assist with make and model.

Windows 7 RTM x86 (Build 7600)

If you plan on upgrading from x86 to x64, you'll have to do a clean install.

Better start backing up everything.

All core to Duo are.

I just entered it in google and had a few thousand hits on that thing.

You say you want to install it on "her" machine?

Please be careful!! backup everything! Favorites, Address Book, Emails, and email accounts, and of course all the files.

Or you will be asking for a good marriage counselor next.

Core 2 duo's are, core duo's aren't. If wishing made it so<g>

Windows 7 RTM

Thanks for the responses.
To clear it up, the only reason I was going to install the x64 on her notebook that has a x86 Vista on it was because that is all I had at the time. I was about to go over to her place and didnt have the time to download a x86 version of 7.
Turns out though, that is what Im going to do anyways. The only way I could have gotten the x64 installation to run was to do it from boot (attempting install in her x86 Vista failed due to the x86/x64 mismatch). I was going to make a bootable iso out of disc I had but I had other programs on the disc.

So it looks like I will just install the x86 Win 7 on hers instead. But one question, even though her notebook only has 2gb of RAM, would installing a x64 OS on a computer with less than 4gb of RAM been beneficial at all, more of a hinderence, or ran just normal?

As I said in my earlier need to have at least 6 gb of ram to see any difference. 12gb will really make a difference

I wouldn't recommend installing 64-bit on only 2GB RAM, because 64-bit Windows 7 has to load the 32-bit processes into memory and this just takes away any benefit you may get from the improved 64-bit system.

If you had 3GB RAM, then I would say yes go ahead.
