Repair Partition Table?


Hello there. Grub cannot load my linux. It says "error 13 cannot load" or something along those lines. Originally I thought this would be due to my partition table being buggered? But I guess not, as I booted into a cd version of ubuntu and fdisk -l displays all of my partitions accurately.

This must mean that the code which boots the kernel at the start of my linux partition was buggered and not the partition table. (I think). How would I go about fixing it? Thanks.

Sure thing. I dont have grub.conf but I do have menu.lst

menu.lst
Code:
# 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		3

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu

# 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
#      password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/
# password topsecret

## Xen hypervisor options to use with the default Xen boot option

## Xen Linux kernel options to use with the default Xen boot option

##      altoptions=(recovery) 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

Okay I just noticed that it says (hd0,2) and it should be (hd0, 1).

I have no idea how on earth that could have possibly been changed from 1 to 2... But I fixed it, thanks for you help!
