w2k was installed before, and everything was working fine, till i tried to format the upartioned and unformated part of my hard drive with bootitng (partitioning software, also lets your boot multiple OS),
boot from xp cd.
it will start loading files, then give you the screen to either install xp or repair,
then choose any of your partitions as selection.
login as administrator.
on command prompt type bootcfg /rebuild (space after bootcfg), it will scan partitons and ask you if you want to add it, and what is the name you wanna give it.
i said (y) for yes
xp for xp partitoin and for the last question i just hit enter.
IT DOES that for all OS you have installed.
then type EXIT and voila
