Partitioning gone bad-deleted /usr
I'm running Mandrake 9.2 (kde) with a 4 gigabyte partition from my XP harddrive. i had a bland 30 gig hdd that i planned to partition as a linux storage bin. Using diskdrake i created an ext 3 partition and mounted it to /usr. I later wanted to change it and mount it under /home and when i deleted it all of /usr disappeared. I no longer can open conqueror or anything that has any part in usr. Is there any way to get /usr back or do i need to reinstall?
