I want to upgrade my Processor and Motherboard but I want to keep the OS setup(dual boot for Ubuntu and Windows7) intact.

Is it possible? What are the problems faced, if any?

Ubuntu will be just fine. The kernel will auto detect and handle everything. Windows on the other hand needs some help to deal with major changes.

With administrative privileges you should use sysprep.

c:\windows\system32\sysprep\sysprep /oobe /generalize 

Put the above in a batch file right click on it and run as Administrator. Do this just before you shut your existing system down for the last time before the actual upgrade.

After the upgrade,on first boot, windows will re-detect all of your hardware.

Is that really necessary for Windows? I'm a Linux guy but I know I've changed processors without any special steps and Windows will correctly recognize them (at least XP and 7). –  terdon Sep 8 '13 at 15:20
    
That's why I love Ubuntu :) –  svineet Sep 8 '13 at 15:20
    
@terdon changing your processor is fine, but this person is also changing there motherboard. –  cybernard Sep 8 '13 at 15:36
    
Windows doesn't need anything done before changing just the CPU. –  Ƭᴇcʜιᴇ007 Sep 8 '13 at 16:15
