trying to run bach file

Running bach file from Recovery console command prompt.
I'm trying to do a manual recover for a corrupted registry file that
prevents Windows XP from opening. I've followed instruction on how to do this
from Microsofts ' knowledge base (article Q307545). It say to save time I
could copy several lines of commands as a text file then use the batch
command in the recovery console to execute these lines. However, I cannot get
the file opened out of my floppy drive. What am I doing wrong?
