Re: debian & fedora together

EXT2-fs warning (device hda3): ext2_fill_super: mounting ext3 filesystem

This sounds like Debian somehow does not detect your Fedora installations filesystem as ext3. Is there an entry in the grub file for this filesystem within the Debian installation?

VFS: Mounted root (ext2 filesystem) readonly
Freeing unused kernel memory: 144k freed
Warning: unable to open an initial console

This might be caused by Debian install having a different method to initialize the system that is related to the 2.4 kernel way of doing things. Fedora and the 2.6 kernel used to error in this way during early 2.5 test kernel days. There are different initializing process between the two kernels. Your best bet is to chainload Fedora in a way similar to what is done to load fireign operating systems, DOS, windows, os/2 and the like.

Using the first installation disk for Fedora, boot into rescue mode, then chroot /mnt/sysimage for the Fedora installation that should be found. Now, type grub-install /dev/hda3 and the Fedora Grub should be installed for the hda3 Fedora installation.

When booted into Debian,add this to your menu.lst file for the Debian grub. This should chainload (hand over process to the Fedora grub installation) and the Fedora boot menu should come up.

title Fedora
        rootnoverify (hd0,2)
        chainloader +1


root (hd0,0)
kernel /boot/vmlinuz-2.4.27-1-386 root=/dev/hda1 ro
initrd /boot/initrd.img-2.4.27-1-386

Fedora Core3:

root (hd0,2)
kernel /boot/vmlinuz-2.6.9-1.667 ro root=LABEL=/1 rhgb quiet
initrd /boot/initrd-2.6.9-1.667.img

I tried changing the root=LABEL=/1 statement to root=/dev/hda3 to no avail. I
am unfamiliar with the '=/1' after LABEL, although I believe LABEL refers to
grub.conf on the Fedora partition.

LABEL=/1 should be root on the Fedora installation and equiv. to a /dev/hda3 entry. The LABEL=/ is probably your Debian installations label.
I assume that /dev/hda2 is a swap partition that is used for each installation.

The rhgb and quiet stuff leaves me a little puzzled, but I suspect that will be revealed in the fullness of time as I suspect they have to do with the X stuff and not the disk stuff.

The Red Hat Graphical Boot Loader is the Fedora Boot screen that does use the GUI for its workings. The quiet entry suppresses the usual messages that the kernel usually displays on the terminal during boot.

John's other points about menu.lst and adding entries with an editor might work as well.
