I'll also note that every time I installed to my external drive I have disconnected my internal drive so as not to mess up Windows.
External install (external hdd or to a flash drive 8G min nowadays)
Doesn't mater what format the drive to the computer. It should work on nearly any computer, the main problems you run into are video driver issues sometimes. So not install other video driver. You should install a 32bit as its far more portable ie 32 bit will work on 32 or 64 bit machines but 64bit wont work on 32.
You dont need to remove the windows drive at all - its just your present level of understanding on how to install.
