Operating system disapears from GRUB after update [SOLVED]

[Technaut]

I run a Kubuntu and Windows XP dual boot system, and I just updated Kubuntu to the latest version. But now my GRUB menu has changed, and Windows is no longer listed on it. How can I fix this?

Um, well whatever following those instructions did, it didn't add Windows back to the GRUB list. Actually, as far as I can tell, it didn't do anything.

Re: Operating system disapears from GRUB after update

Do you have in the /boot/grub/menu.lst something like this:

### END DEBIAN AUTOMAGIC KERNELS LIST

# This is a divider, added to separate the menu items below from the Debian
# ones.
title		Other operating systems:
root


# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/hda1
title		Microsoft Windows XP Professional
root		(hd0,0)

I used to, but now all that is in there now is the Kubuntu kernals.

You could add it there.

Qqmike chapter:

- - - Where to put Windows in your menu.lst:

GRUB Page has a example of GRUB menu.lst file
http://users.bigpond.net.au/hermanzone/p15.htm

7 grub
This is an entire GRUB menu.lst file out of one of my computers. It should be fairly typical for a dual boot computer with one hard disk.

Make sure you add it after:
### END DEBIAN AUTOMAGIC KERNELS LIST

Everything between
### BEGIN AUTOMAGIC KERNELS LIST
and
### END DEBIAN AUTOMAGIC KERNELS LIST
Is overwritten by update-grub script (which is run when kernels or grub is updated)

Re: Operating system disapears from GRUB after update

Well, not much else new to say here. It’s easy enough to add an entry for Windows – edit as root the /boot/grub/menu.lst to include something simple like


title Windows XP again
rootnoverify (hd0,0)
chainloader +1

assuming Windows is on the first partition of the first hard drive (booted in BIOS).
About the only mistake you can make is forgetting to File > Save and File > Quit when done editing (now, how would I know that…?).

Personal preference:
If Windows is your default OS, then you might want to put it just BEFORE the line *** Begin Automagic Kernels list. That way, it will always be in position zero, so the statement default=0 will always work to boot XP by default. If you get another kernel update, and if Windows is after the *** End line, since the kernel update goes between *** Begin and *** End, and that would bump XP up one number in the list. It's all explained in the How-To referenced above—where to put Windows. If Windows is not your default OS, you can put it anywhere before or after the *** Begin--***End section.

Thanks for the help, I added the Windows entry outside of the auto kernels list and it worked.
