Before you install the Windows 2000 Professional desktop operating system, make sure that your computer meets the following minimum system requirements:
* 133 MHz or more Pentium microprocessor (or equivalent). Windows 2000 Professional supports up to two processors on a single computer.
* 64 megabytes (MB) of RAM recommended minimum. 32 MB of RAM is the minimum supported. 4 gigabytes (GB) of RAM is the maximum.
* A 2 GB hard disk that has 650 MB of free space. If you are installing over a network, more free hard disk space is required.
* VGA or higher-resolution monitor.
* Keyboard.
* Mouse or compatible pointing device (optional).
Sounds like your hardrive might be to small.

How to burn a live CD of Linux Operating System in Windows

Your specs are too light for Ubuntu but Puppy 3.01 or 2.15 should run OK.
You can either run Puppy Linux off of CD or install to Hardrive as what is called a frugal install. The newer Puppy 4 series might be to advanced for your system requirements is why I suggest 3.01 or 2,15. You'll know if Puppy 4 won't boot up.
Windows doesn't support hardware like yours any more. But Linux does. You will have to learn a new way of thinking if you decide to run Linux. I have no problem running Linux and I am just a regular home user.That is the best I can do for you.
Maybe a Windows member can help you with Windows matters and installation.
