please re-install a copy of the above file.
i tried to search this at microsoft knowledge base but non of theose could help me.

While you can copy the original hall.dll from somewhere else to the pc, it has to contain hardware info of your pc or else, you'll see the error over and over. In shorts, you're not gonna be able to fix it.

Try repair install. Insert windows cd, boot it up, when asked, select repair. It still may not work that way though.

Let it be a lesson learned: don't mess with partitions unless you have backup of your data.
