I have recently purchased the Windows 2000 Professional CD on E Bay. I am having the problem installing the same on my laptop. I am currently running my laptop on Windows Xp Home Edition.

When I try to install Windows 2000 then initially I get a message "The version of the CD id older than the installed on your computer. The Setup will now disable install functionality".

After this the install link is disabled.

Can anyone please help me to overcome this problem.

    Boot to the 2000 CD and install it that way.  Don't try to run setup from Within Windows

    If that does not work, try this:

    1. make sure anything you don't want to loose is backedup!
    2. go into the Windows folder and Rename WIN.COM to WIN.OLD (I think it is still called that in XP). Reboot with the CD and install.

    Whenever you go to Dual Boot OS's, the recommended configuration is to have different partitions for each.  You will also start with the Oldest OS FIrst, in this case 2000.  After Installation, you would then put on XP and it will appropriately make the changes to the boot.ini file.  For your best system stability and sanity, I would start from a clean slate and rebuild the box appropriately.
