Hello.
To be safe I bought an new identical 80gb sata harddrive to install
Fedora Core 6 on. The old one has Fedora Core 5 installed on it. I
installed fc6 on the new drive with the old drive unplugged. I then
plugged the old drive back in. After configuring /boot/grub/grub.conf,
I was able to see and switch to both systems on their own drive from
the fc5 initial boot screen. Everything was working until I decided to
enter the boot menu and boot into fc6 on the new disc directly. I get
this message from dmesg on fc5:
hfs: unable to find HFS+ superblock
VFS: Can't find ext3 filesystem on dev sdb.
Using the rescue disc I chroot /dev/sysimage -> nano
/boot/grub/grub.conf. But grub.conf is empty. I was able to do this on
initial install to get the grub.conf entry info to add to the fc5
master grub.conf.
I can can still boot into fc5, but when I choose the fc6 entry on the
fc5 initial boot screen, I get a lock up and kernel panic.
[root@corefive ron]# mkdir /mnt/fc6hd
mkdir: cannot create directory `/mnt/fc6hd': File exists
[root@corefive ron]# mount /dev/sdb /mnt/fc6hd
mount: you must specify the filesystem type
[root@corefive ron]# mount -t ext3 /dev/sdb /mnt/fc6hd
mount: wrong fs type, bad option, bad superblock on /dev/sdb,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
[root@corefive ron]# dmesg | tail

VFS: Can't find ext3 filesystem on dev sdb.

How can I correct this? Please help.
Pre Thank You,
