GRUB dual-booting problems

Well, I have a dual-boot setup on my system with Windows XP all by itself on the first hard drive, and Kubuntu on the second. I keep having problems whenever I want to boot into Windows from Grub. Most of the time when I scroll down to the Windows entry and hit enter, my system will just reboot. I usually get it to boot after 2-3 tries, but have had it go up to 9 tries before. Does anyone here know how to fix this?

Thanks in advance,

it sounds like your GRUB might be compiled incorrectly. can you boot to Linux ok?? ifyou can then i would suggest going to root and then going to

/boot/grub/menu.lst

copy and paste that here to see if your menu.lst is screwed up.

Worse case scenario is your Master Boot Record (MBR) on windows has been corrupted.

I do know that Kubuntu is still in its early stages and can be quite buggy

Another option is to try LILO and see if that fixes the issue.

Here's the menu.lst

# 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'.
default 0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 10

## 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

#
# examples
#
# title Windows 95/98/NT/2000
# root (hd0,0)
# makeactive
# chainloader +1
#
# title Linux
# root (hd0,1)
# kernel /vmlinuz root=/dev/hda2 ro
#

#
# Put static boot stanzas before and/or after AUTOMAGIC KERNEL LIST

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default optons below

## 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 specifiv 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=root=/dev/sdb2 ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd1,1)

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

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

## 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

## nonaltoption boot targets option
## This option controls options to pass to only the
## primary kernel menu item.
## You can have ONLY one nonaltoptions line
# nonaltoptions=quiet splash

## 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

## ## End Default Options ##

your Grub is set correctly. which brings us back to your MBR. boot into windows, I understand that it may take a few times for you to get into it.
After you are in Windows put your Windows XP disk in the drive then click on Start>run and type in cmd

in the window that opens up type the following

sfc /scannow

note the space before the /
let it run and then reboot your system

let us know if this solved your issue or not :tazz:
