Thanks for your reply Dave.

Yes, the missing "/" is a typo.

I know next to nothing about LVM and just let anaconda do whatever it
preferred. My preference would be a /home partition to protect my data
during future upgrades but I need to learn how to save to cd/dvd and
that would be better protection.

I'm confused by your question "did it run out of space on /boot?" I
don't know how it would run out of space. I believe I made my original
Fedora 7 /boot partition much bigger than my FC2 /boot partition but I
can't find my records and anaconda might have changed it to whatever it
wanted - I believe I answered 'yes' to anaconda's question "Erase all
partitions and install Fedora?" Let's let the computer tell the tale.

Here is a copy of the output of fdisk -l and fdisk /dev/sdb with x then
p commands. I used the Negus Fedora 7 book's Live cd.

[root at localhost ~]# fdisk -l

Disk /dev/dm-2 doesn't contain a valid partition table[root at localhost
~]# fdisk /dev/sdb

The number of cylinders for this disk is set to 24321.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): x

Expert command (m for help): p

Again, using the Live cd from Negus' Fedora 7 book (hopefully that would
produce the same answers as a rescue cd would?):

[root at localhost ~]# fsck -f /dev/sb1
fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
fsck.ext2: No such file or directory while trying to open /dev/sb1

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate
superblock:
e2fsck -b 8193 <device>

Unfortunately as I wrote above I don't have records of the superblocks
from when I set up the partitions if that is what fsck is referring to
and the disk was probably repartitioned by anaconda in any case.

It will take me a bit longer to answer the questions on grub but I can
use the Negus F7 Live cd that I used to cut and paste the outputs above
between the 2 computers via floppy.

Thanks again for your reply Dave. I hope these details provide
interpretable clues to the problem.

One point, the computer rebooted 2x from disk without problem before the
updates.
