EDITING GRUB TO LOAD KNOPPIX

[Drool King]

Hiyall!

Need help on booting with knoppix. I have XP, Knoppix and FC3. I installed XP and Knopix (which was running OK) and when I installed FC3 GRUB overwritten the LILO and it is now showing

root verify (hd1,0)
chainloader +1

but with this, knoppix won't boot.

Please help.

Can you post your entire GRUB configuration file? And a list of your partitions would be helpful: the ones that have the /boot and / directories for Linux as well as the one with XP, kind of like this:

• hda1 XP
  hda2 Knoppix /
  hda6 FC3 /boot
  hda7 FC3 /

Drake,

My config is:

hda XP
hdb0 Knoppix
hdb1 FC3

Grub shows

(WinXP)
root verify (hd0, 0)
chainloader +1

(FC3)
root (hd1,0)
kernel /boot/vmlinuz-2.6 ---- (i forgot the other string)
initrd/boot/initrd-2.6-----(i forgot the string)

Knoppix
root verify (hd0,0)
chainloader +1

Thanks for the fast response.

From looking at your grub.conf I see that your Xp and Knoppinx are both (hd0,0)
which means that are both on the first partition of your first hard drive, this is not right and you should only have Xp set like this since it is the only thing on your first hard drive (hda).

Secondly your grub.conf states that fedora Core is (hd1,0) which means it is on the first partition of the second drive, but you stated that this partition had knoppix in it.

So ether you have overwritten Knoppix with Fedora Core, so that Fedora is now the only thing on the first partition of hdb, or you don't remember correctly which partition is which and you have Knoppix on the second partition of your second hard drive.

Fedora core must be on the first partition of the second hard drive since it says so in the grub.conf, and you don't have trouble booting to it;

So ether Knoppix is no longer on your system, or you have the names mixed up and it should be (hd1,1)

dylunio is right. Here's the breakdown:

Summary
OS    You think   GRUB thinks
XP       hda      hd(0,0) = hda1
Knoppix  hdb0     hd(0,0) = hda1
FC3      hdb1     hd(1,0) = hdb1

hda is a drive, not a partition. Maybe XP is on hda1?
hdb0 is not right. Linux's partition designation starts counting from 1, not zero like GRUB does. My guess is Knoppix was probably on hdb1, where FC3 is now.

It's always a good idea to take careful notes when doing things like partitioning to make it easier to recover from misunderstandings on your part or the software's (like when you reinstall Knoppix).
