Question Grub Issue


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.

Vijay

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).
timeout 5

# Pretty colours
color cyan/blue white/blue

## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line) and entries protected by the
# command 'lock'
# e.g. password topsecret

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=/dev/hda5 ro ramdisk_size=100000 lang=us apm=power-off nomce vga=791

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,4)

## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=false

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery mode) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all

## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

## ## End Default Options ##

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