Description of problem:

I tried to upgrade a FC6 machine to FC7t3 using the DVD. Anaconda didn't find
the grub config. I asked it to make a new installation of grub and the resulting
menu.lst had incorrect numbers for the HD, eg. (1,2) instead of (0,2).

The symptoms were: grub menu behaved erratically (unable to edit boot commands);
grub wasn't able to load a kernel, and the machine reset continually.


Version-Release number of selected component (if applicable):
FC7t3 anaconda
Dell Inspiron 6000 (ICH6M SATA Controller, /dev/scd0, /dev/sda)

How reproducible:
Haven't tried to reproduce it, but expect it will reproduce easily.

Steps to Reproduce:
1. FC6 machine with SATA disk as above
2. Upgrade from FC7t3 DVD
3. Observe non booting and grub misbehaviour
  
Actual results:
non booting and grub misbehaviour

Expected results:
successful upgrade, booting and grub functional

Fix:
I used the rescue disc to boot and edited the /boot/grub/menu.lst to (0,x)
instead of (1,x) throughout, and the FC7t3 install was fine.

The edited (working) grub.comf. Note the comment still refers to root (hd1,2):
