Description Bowe Strickland 2001-03-30 16:50:17 EST
Using 7.1-rc2, I overwrote /dev/hda w/ image of 
dhcp-kickstart-bootnet.img (to speed up loading of 

	cat dhcp.ks.bootnet.img > /dev/hda

upon rebooting, using TUI ftp install, anaconda 

fdisk error: cylinder boundaries don't match drive
geometry (naturally, i just hosed my MBR...)

my *only* option was to skip drive, resulting in
a "no valid drives found" error and a tailspin...

from the command line, fdisk knows how to reset the mbr.
the installer should offer this option as well...

as i understand it, currently, if your MBR is hosed, 
anaconda won't install. (assuming you don't know 
enough about fdisk to go to the command line).

thanx!  --bowe

We will consider different behavior in the future - admittedly your case is an
extremely rare incidence (most users do not mess manually with the boot sector).

You can just goto VC2 (cntl-alt-f2) when you get to this point in the install and

mknod /tmp/hda
fdisk /tmp/hda

and reset it as you like.
Comment 2 Bowe Strickland 2001-04-02 13:03:01 EDT
agreed, but note that VC2 is not an option for kickstart installs (where
'wipembr yes' has been defined!) (although inelegant scripting of fdisk through
%pre would be possible).

FWIW, i'm not sure it's "extremely rare" for someone to be handling an
unitialized drive at install time.  I've been frustrated with other
"unnamed vendors ;)" providing an installer that demanded that I had
an initialized MBR before.  For an installer not to be able to trivially 
configure blank media seems a bad assumption.

thanx!  --bowe

As msf said, this is something we will consider for the future.  It's much too
late in the cycle to consider this for the current release.  Deferring.

Should work better with roswell.
