I recently installed 8.04 (Heron) on my Sata drive. I have Win XP on another drive (Pata) in this pc. Before the upgrade to 8.04, I was using 7.10 with the dual boot & I got the selection screen at bootup.

Now after this install, I get the selection screen & XP is listed there, but when I select it, I get "NTLDR is missing". If I go into the BIOS & boot to that drive first, XP will load just fine, so I know it is okay.

I need to know how to get Linux to allow me to dual boot as before. How do I configure this to work? I am sure it is an easy fix, but I am a linux noob, so I need your help!

Thanks in advance!

Select Ubuntu and boot from it. Post the output of fdisk -l and cat /boot/grub/menu.lst. Issue both command on your terminal.

Boot with the live Ubuntu cd.

When you get to the desktop open a terminal and enter.

sudo grub

This will put you into a "grub>" shell (i.e. the grub prompt). At grub>. enter these commands

grub >find /boot/grub/stage1

Whatever was returned for the find command use it in the next step (you are still at grub>.

grub >root (hd?,?)

Again use the value from the find command i.e. if find returned (hd1,5) then you would enter root (hd1,5)

Next enter the command to install grub to the mbr

grub >setup (hd0)

Then exit the grub shell

grub> quit

Then reboot without the CD.

GRUB needs a edit.
Go to Terminal and type in:
sudo gedit /boot/grub/menu.lst
And tell us what it says!

Wow, thanks for all the replies, everyone! I do remember doing this the last time for dual boot, but I am hesitant on making any changes when I don;t know what I am doing.

Try removing/commenting this

Okay, here is what I changed it to, saved & rebooted. When I select Win XP to boot into, it goes to a black screen & says "starting up" & that's it. At least the "NTLDR is missing" is gone, but I still can't dual boot.

Here is the fdisk -l & menu lst; Did I miss something somewhere?

You're still going to need those map lines--you're essentially chainloading a windows drive in second position (http://www.users.bigpond.net.au/hermanzone/p15.htm#Windows_on_a_non-first_hard_disk). If you have only two hard disks, then windows should be:

Thank you, I got it working now. I will save this thread for future reference!

Again, thanks to all for replying!
