Windows 7: Dual boot 32/64

I'm a newbie to beta software, so please forgive my ignorance on this subject.

I wanna see what all the buzz about 64bit is about.

I downloaded and installed RC 7100 32bit and running it with a dual boot to XP sp3 32bit.

Could I dump the RC7100 32 bit (by reformatting the partition) and installing the 64 bit version and still dual boot with XPsp3 32?

Hello Welcome to SevenForums,michaelst

Hope that you have a good stay here on SF. Yes you can if your hardware is capable of it. You can keep your xp install intact and install another version of win 7 with no problems. Hope this has helped, lm

You can also Triple boot, install Windows 7 x64 (if your system allows) andwhen ask select a NEW CLEAN Partition. just like you installed Windows 7 x86. Only now you can pick and choose which OS to boot into...
Then you can compare Windows 7 x86 and Windows 7 x64. simply by rebooting an pick.

Now before I reboot I simply start -> msconfig -> select boot -> and check the OS I want default. it then says You must REBOOT before this works... Of course you want to REBOOT to your default.

Triple Boot.
