Can I uninstall windows 2000 and replace with windows 98?

Yes.

But why would you want to?

You can uninstall and reinstall any windows program as long as your computer has the capacity to handle the size of the program. As you will be going down in size, you will have no problem

Yes, or partition your drive and put both on, then you will be given the option to start in 2000 or 98.
Just get Windows XP Proffesional...
sure ya can. if your haveing a issue with it not letting you do it easyly then just make a start up disk. then once ya boot to dos you should be able to /format c:\ .

if for some reason it will not let you format you may need to fdisk and unmount and remount then format the drive but these are not things that take to long to do.now if oyu dont know how to use dos you may want to ask a friend to help you or you could mess up your partitions on your hd and make life harder on yourself.
Actually, that's very possible. Just format (completely empty your PC) and reinstall it. But, why would you want to do that? That's kinda pointless isn't it?
YES, backup all files you want to keep EXTERNALLY, Use 98 disc and reformat the HD, then install.

I can sympathize with your problem. Newer programs almost ALWAYS require newer computers due to the size of the OS, and the extra "bells and whistles" they add.

I can't understand why so many people are against you using an older OS.

I have several older systems and still use MS-DOS for what it is good for, such as "control". (On a 200MHz CPU, 33MHZ bus, 16MB RAM; it will be up and running BEFORE WinXP can finish booting on a 4GHz CPU, 400MHz bus, 1GB RAM, !!)

I am writing this with Win98SE, but I also have an older UNIX, and several Linux, and Win3.1 for different uses; as well as WinXP for some things.
