you need to defrag your pc and use partitioning software like partition magic to make 2 partitions of a decent size.
now you go to a dos prompt and type
you now edit your c:\boot.ini file with notepad and add the line
attrib -s -h -r boot.ini
you will have to change the 1 in the partition to what ever partition you will be installing win 2k on. im assuming it will be 2.
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect
