[UCLA-LUG] system failure

[ninalin@ucla.edu]

okay, I was trying to configure ethernet card on my linux partition. 
it's on hda7.  second partition.
anyways, I could not get ethernet to work so I try to reinstall redhat 6.1 on second partition.  somehow?? the redhat image got written in my boot sector I think, now every time I start my machine, I would see the read hat reinstallation screen instead of window.  
I did 
fdisk /mbr and sys c:
but it didn't see to help. then I run window setup.exe 
from c:/windows/options/cabs/setup.exe
but that didn't do it either. 
now I am trying to get back into my machine using redhat boot disk. 
somehow, it loads default from hda5, and it have init error
I know these two command are needed
at LILO prompt
linux root=/dev/hda7
linux init=/bin/ash
but I cannot get both line in at LILO prompt, so 
does anyone know how to 
1. fix it so I can get rid of linux image on my boot sector? 
load from windows?
or get into red hat ?
thanks.
