I have a CentOS 5 machine in which I'm trying to remove lvm. I dd'ed the

point to the correct device.
When the system boots it's still looking for lvm. I can restore the
system back to where it was with lvm, but I'm not sure what step I'm
missing to stop the system from looking for lvm.
Extract the initrd, edit the init script (I do not remember the name)
and compress initrd again. I had to this some time ago after renaming a
Volume Group. There is some lvm stuff hardcoded in this script.
Markus,
Thank you for the suggestion. I'm very close, I think. I used the
instructions here for working with initrd's script:
http://www.thegeekstuff.com/2009/07/how-to-view-modify-and-recreate-initrd-img/
I'm still having a problem booting up. I can't seem to figure out what
the proper settings should be in initrd. When I boot I get:
