Solved Dual booting 32bit and 64bit system?

[Johncy]

I recently got a game that only run in a 64 bit system and my PC is running on Windows 7 ultimate (32 bit). In order to run the game, I want to make another partition and install 64 bits windows 7 ultimate.
From what I understand, since my PC only has 2GB of RAM, it run faster on a 32bit system. So, I am planning to dual boot (32 bits and 64 bits). For general use, I will just launch the 32 bit windows, then only use 64bit when I want to play game.

Before doing all of the things mentioned above, I got a few questions:

1) Is this the "best" or most effective way trying to achieve what I want?

2) I only have one windows 7 ultimate license, so I am not sure if it is possible to dual boot this way? Or it will automatically activate the license when I install 64bit version since I am using the same PC?

3) Is the steps below the correct procedure?
- Partition my hard-disk
- Boot into windows 7 iso from usb
- Install windows in new partition
- Done?

4) Assuming I am using steps mention in #3, both system will be on the same hard-disk and PC, only different partition. Will I need to install driver again?

Appreciate your help, thanks a lot.

You will need another windows 7 Ultimate license for the 64 Bit edition, Good Luck with that.

You have to add all the drivers to the 64 bit version, it`s a brand new install.

I would add as much memory as you can afford or the motherboard supports, the 32 bit version will use 4GB or less, that`s not an issue, you really need to raise it from 2 GB anyway.

Put at least 8 GB in if the motherboard will support 8, you`ll be fine
