I am new to ubuntu the computer came with it already installed as the OS. I have an insulin pump that only uses windows. So I need to take ubuntu off and install windows 2000. I have tried setting bios to boot from cd-drive. it starts to load windows takes 1-2 minutes and says unable to install. This has been the only way any response from windows has been acheived. I am exhausted with this situation. I am not a computer programmer and I need HELP.
