I Installed Knoppix to HD first on partition hda6, used this well for a few days and then to hda5. Now it only boots hda5. No longer able to boot hda6. Did google for this. Uses Grub Bootloader. However, there is no direct answer.

I tried to edit the present bootloader to point to hda6 but then this said wrong file system and wouldn't boot.

Have a lot of customizations on hda6. In /media/hda6/boot there is a file called previous bootloader. Would appreciate if someone can help me replace this back. Please assist.

Thanks.

It would be helpful if you'd give the exact error message.

Atleast post your menu.lst so we could see your setup info.

Error message: Wrong or incorrect file system, when I replace hda5 with hda6

Menu.lst as requested below:


# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).

Issue resolved, I cut and paste the Menu.lst from hda6 install into hda5 install and booted. Now both are booting. Thanks a lot.
