  • Yes you can, but be aware that 32-bit Windows will not take advantage of all your RAM if you have more than about 3.5GB.

  • It doesn’t matter which one you install first, but remember that the first partition you install to will have the boot files on it.

    So, if you intend to remove one of the operating systems in the future, make sure the unwanted one is the second one you install, otherwise it’s a somewhat fiddly repair process.

  • I don´t know why do you need it.

    I need it because sometimes I had to check some situations in old 16bit applications. I decided to use Hyper V and virtual machine for this purpose . Seem's to me to be more comfortable. I can use both systems in time.

  • If you have a desktop with an available external 5.25 bay, Antec makes a HHD drive bay http://www.newegg.com/Product/Product.aspx?Item=N82E16817991008 that you can use to support the 2nd OS without any of the issues that sometimes occur with dual booting.  Conceptually, it is similar to the floppy except you plug-in a standard HHD.

    You install the OS and the app's you want for it on this plug-in HHD. Then whenever you need this OS, just plug in the drive and reboot with it.  When you are done, just unplug and reboot in your primary OS. 

    I used to run dual boot XP/Vista and later, XP/Win 7systems.  This drive bay simplifies the process.  It also is great for back-ups.  I back-up on a SATA HHD now instead of a USB external -- much faster.

  • Hi all,

    Sorry for delayed response.

    First of all thanks a lot for your replies. Actually I'm into testing and want to test the software on both 32 bit as well as 64 bit Windows 8. This is the reason I want that machine to be dual boot.

    What I understand from above replies that I should be able to do this without any issues. Can you guys let me know which OS should I install first? 32 bit or 64 bit? So that I can get dual boot menu at the start up...

    Thanks once again
