Windows 7: Installed Win7 32-bit. Now want 64-bit

Installed Win7 32-bit. Now want 64-bit

I have 2 x Windows 7 partitions on my system, both of which are 32-bit installations. I'd like to upgrade one of the installations to 64-bit (I do have a 64-bit machine BTW). Are there any caveats I should know about? I've gathered that an 'upgrade' requries me to choose the Custom Install option which loses all my data files and 3rd party programs but that's no problem; I can back them up and replace them. Anything else I should know about? e.g. will my other partition be left intact?

Only check for 64 bit drivers.

Windows 7 Ultimate SP1 64-Bit
 
 

Have a read here: 32-bit and 64-bit Windows: frequently asked questions

You can't upgrade, it'll need to be a Custom install.

You might need to edit the boot screen as well: BCDEDIT - How to Use

Your other partition will be left intact.
