Hi,
You really need to determine what is causing your computer to fail on boot.
How old is this computer? Have you run any hardware diagnostics? It could
be a failed hard drive, or failed motherboard.
If Windows 2000 is having problems due to failing hardware, installing any
other operating system would be futile.
