|First// make a new ERD; keept handy - just in-case.|
Then edit boot.ini so that it looks as follows:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows 2000 Professional" /fastdetect
In other words - delete the last entry "only".
(To find and edit the boot.ini: g via MyComputer\Properties\Advanced-tab\startup and r recovery\Settings - Edit button...)
Reboot system to ensure/verify you still can (just in-case you inadvertently deleted the wrong entry).
Once back up OK open Explorer - locate and delete the folder "winnt". That is the original installation folder...
When W2K goes in it "usually" calls itself winnt if that name isn't already in use in "that" partition. A second installation to the "same" partition will be called windows.... If there are two or more installations of W2K, each in a separate partition. then each will be called winnt... (unless in any situation/installation "you" choose to change the default folder name proffered at time of a given installation).
Empty Recycle-bin; defrag drive; reboot; renew ERD and keep safe.
