Description of problem:
I have two hard drives with Fedora on the primary master and Windows
XP on the primary slave. After installing Fedora, when I would select
the Windows boot option from GRUB it would drop me into a GRUB shell.
After Googling I found out that grub.conf was missing a statement. I
added the map statement and it now boots as expected.

title Windows
    map(hd1, hd0)
    chainloader +1

Version-Release number of selected component (if applicable):
Fedora Core 1 installer

How reproducible:

Steps to Reproduce:
See description.

The map statement isn't always needed (in fact, in most cases it's not
and using it will break things).  The only time it's needed is if you
originally installed windows when the drive was the master and then
later change it to be the slave.
Comment 2 Steve Fox 2004-01-14 16:00:11 EST
Ah. That was the case for me. I installed XP when it was the primary
drive (I think it failed installation when it was a slave), then later
moved it to the slave. Thanks for the response.

Sorry to dig up such an old bug, but is there any plans to try and detect where
this is needed or provide an install-time option for it (since the bug is closed
