Grub

JamboUK · 02-16-2007, 04:07 PM

Hello,

Was wondering if anyone can help with this little niggle.

I have a dual booting base unit running Ubuntu and XP. I predominately want it to boot into XP so in Grub this is the default OS for boot up.

I have set this up following the guide on the Ubuntu Guide website. Works no problem.

BUT whenever the Ubuntu kernel is update a new Grub Menu is created and my old one overwritten and thus taking the Windows XP entry with it. I then have to go back in via and re-enter the XP entry at the top of the list.

Anyone got a better method so the XP entry remains intact despite a new kernel download. Thanks in advance.

sure - if you look in /boot/grub/menu.lst, you will see some lines like this:

Code:

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

... that last line looks suggestive doesn't it? What happens when you uncomment it?

Put your update after the "### END DEBIAN AUTOMAGIC KERNELS LIST" line.

Then they won't get changed.
Gawd I hate auto-updaters - Debians included.

If you uncommented it, it will get overwritten by default configuration.
You have to replace false by true and leave the leading #

I like the debian autoinstaller for kernels! What's wrong with it?

Ask the OP - QED.

How to disable the autoinstaller:
Comment the line postinst_hook and postrm_hook from /etc/kernel-img.conf
This way, update-grub won't be launch.

Ah - I stand corrected: excuse me.

When I provide minimal information, I should remember not to be misleading.

These commented thing are misleading also

Anyway, for the OP, just follow what syg00 said previously.
