Windows 7: Using a secondary drive with 64bit when primary is a 32bit

Using a secondary drive with 64bit when primary is a 32bit

So earlier this year I constructed my first computer, which I sunk about 2k into and made fantastic :). But, having no experience, I installed a 32 bit Windows 7 OS, thereby limiting my available RAM. Since I am a gamer, this is a bit of an issue. Now I have a new SSD, and I was wondering if I could simply load a 64 bit OS onto that drive and boot from there, thereby avoiding the reformatting of my current drive.

The primary drive is a 1TB regular hard drive, the secondary is a 64Gig Samsung 830 SSD.

Try downloading and burning a 64bit ISO image, and just use the same activation key. Note that it must be the same version of windows!!

There is no difference in the formatting of a drive for 32 bit Windows vs. 64 bit Windows.

I hope that you understand that you'll have to re-install every application on the new Win7 X64 installation. (At least, those programs that used installers.)
