Hello everyone,
I'm new to Ubuntu and i'm facing a weird problem and dont know what to do.

I had 2 hard discs. One 80 GB PATA and a 160 GB SATA. I have Windows XP and Ubuntu-9.4 on my 80 GB hard disc. Currently my 160 GB disc crashed and I started getting
"GRUB READ ERROR"

After that I removed my crashed Harddisc and then PC automatically booted in Windows (No GRUB menu). I was not getting GRUB menu so I inserted Live CD and did following steps


sudo grub
find /boot/grub/stage1
then I noted returned location and did

root (hd#,#)
(where #,# is returned location like (hd0,1) but I dont remember exactly what it was
then I did

setup (hd0)
quit

This did it and I got Grub menu and started booting correctly. Then I tried to connect my crashed HDD and surprisinly it worked one time. After that when I try to boot in Windows, I get error saying

Error 21: Selected disc does not exists.
Press any key to continue...

When I press any key, PC restarts. I dont know what to do. I am able to boot and work in Ubuntu but not in Windows. I have removed my SATA 160 GB disc. but I am not able to do anything about Windows. Please help... I need Windows to work on my academic software project.
Thanx

Let's get a better look at your setup & boot process. Boot the Ubuntu Live CD/USB. Choose "try ubuntu without any changes", when the desktop loads come back here and use the link in my signature to download the Boot Info Script 0.35 to the desktop. Once on desktop open a terminal and run this command
sudo bash ~/Desktop/boot_info_script*.sh This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

Boot into Ubuntu and open a terminal, run this command
gksu gedit /boot/grub/menu.lst
That is a lowercase L in .lst

Scroll to the bottom where the windows entry is. Change this:

# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sdb1
title Microsoft Windows XP Professional
rootnoverify (hd1,0)
savedefault
makeactive

Click Save on the top toolbar & close file. reboot & try windows booting windows again.

Ok, looking at your boot info script it looks like the 160 Gb disk you removed booted first and had GRUB installed on it. When you removed that your machine would boot into Windows because it's bootloader was on MBR of 80 GB disk. This is supported by the fact that your menu.lst in Ubuntu (sda2) looked like this:


# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sdb1
title Microsoft Windows XP Professional
rootnoverify (hd1,0)
savedefault
makeactive
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

Note it says your windows is installed on sdb1- this means your 160 GB disk was booting first and was designated as (hd0). That is where the map lines came in. Windows needs to be on a primary partition on the first disk that boots. When 160 GB disk booted first you needed the map lines to "trick" or "entice" windows into thinking the disk it is installed on boots first.

Now you have the 80 GB disk only so that disk now becomes (hd0). So windows is no longer on (hd1,0) it is now on (hd0,0).

Since windows is now on the first disk that boots you no longer need the map lines.

Savedefault & makeactive really aren't necessary.

GRUB now takes over at boot because earlier you put it on MBR of the 80 GB disk with the operation you posted originally.

Any other questions ask!
