Error Msg with RH7.2 Network Install

["Sendur Sellakumar" <SSELLAKUMAR san rr com>]

Hi All,

I am getting this problem with one of my machines on a network install.
The RH installer connects to the ftp site and then stats "Retrieving
etc...."

Then, the installer pops up with this error message:
***********
Error mounting /dev/loop0 on /mnt/runtime (invalid argument).
This shouldn't happen , and I'm rebooting your system now.
***********

Anyone know the source of such an error, seen it before?  A possible
resolution?  

Is it possibly some sort of RAM disk issue?  Mandrake's installer 
stated
that it could not uncompress its second stage ram disk...is it similar
problem?

Thanks!
