[WBEL-users] Screwed by a CentOS4 install test

[Jack Glendening]

I think I finally got the correct return address on this one - I 
apologize if any duplicates turn up on the list.

I had sent a followup email to someone who sent a private email telling 
me about using Shift-PageUp to read load messages which had scrolled 
off the screen, which proved useful.  But I should also have posted a 
follow up to this list.   Sorry.

Trying to use grub command line prompts based on others' advice was not 
working, so I  recovered boot control to my "normal" hda1 (with label 
/boot) by using my  original WBEL 3 disks to install it to an unused 
partition while writing the  boot loader to hda1 (without reformatting 
it).

I then replaced the grub.conf that produced  on hda1 with my old 
grub.conf and booting then gave me my WBEL3 kernel load with the 
loading errors as before.  Scrolling back to read the messages, I 
googled on the "duplicate filesystem" error message there, finding it 
likely  resulting from two partitions having the same name.  And indeed 
I found  two partitions labeled "/", though don't know how that 
happened.  Renaming the non-WB one got things working again. 
So I am mailing this from my normal machine, not my laptop. :-)
