How do I (re)move Ubuntu Memtest?

D.K.

I have Ubuntu as a dual boot and Windows (used to) boot by default.
I'm not too sure what I've done but I now have Memtest booting up. Could some kind person please advise me on how to remove Memtest or change the boot up order.

Thanks,

D.

Assuming you're using the GRUB boot loader, all you need to do is to edit the file /boot/grub/menu.lst, as root.

In a terminal window type:

sudo gedit /boot/grub/menu.lst

Look for the "Default 0" or similar statement. The number in that statement corresponds to the entry number in the kernel list at the bottom of the file that you want to run by default, starting from zero and incrementing as you go down the list.

haven't left the disk in the drive have you?

Thanks mdbarber but I have a dual boot...1 boot wasn't enough!

Thank you fwor also. What you say sounds familiar, I'll give it a go later.

Cheers!

You need to edit the file /boot/grub/menu.lst, as root.
In a terminal window type:

sudo gedit /boot/grub/menu.lst

Cut and paste to move the required boot option to the top of the list.
Dont forget to save

Hi Linbox,

I think I followed your instructions OK...memtest is now up the list. Windows is at the bottom so it should boot by default, well it used to but even though it still is at the bottom Ubuntu now boots by default.(2nd from the bottom)
Do you know of a way I can get good old Windows to boot first again?

Many thanks,
D.

Another way to save faffing around with menu.lst, is to use SuperGrub.

http://www.supergrubdisk.org/
(Download the CDROM version using the links on the right)

It'll re-build your grub options. I use it whenever I've reinstalled windows and its killed grub. Very handy. Easy to use too.

GRUB starts counting from the TOP of the list of OS's. If you have no DEFAULT statement (usually near the top of menu.lst) then it should start the one at the top of the list.

If you have a DEFAULT statement then the number following it should correspond to the entry number in the list, and the numbering starts from zero (i.e. count down the list the number of times it says TITLE to the one you want to start and subtract one from that number).

Wolfman - good suggestion. Just downloading it now to give it a try...

Sorry, I didn't know you had replied...I didn't get e-mailed.

fwor, I do have default but don't see any numbers?

Wolfman I think your suggestion might be better. I'm obviously not a good faffer When I click on the CDROM which options should I use?

Supergrubdisk looks quite good, but it's more complicated than you need just to change the default OS - you just need to change or add one number to the file.

Here's an example - note that every line that starts with a hash symbol is a comment and is ignored by GRUB.

The "default 4" points to the fifth item in the kernels list which in this case is Windows XP.

# 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'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.

default 4

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

<snipped for brevity>

## ## End Default Options ##

Hmmm I get your point, but asking the average person to edit a system file is harder. What's a kernel list, where does it start, is their's differently setup etc... If they're willing to learn about Linux, not such a problem, but if they just want to get it fixed, then it's harder.

You can go here:
http://forjamari.linex.org/frs/?group_id=61&release_id=620#620

And download: super_grub_disk_0.9726.iso

If you're running Ubuntu 8.04 Hardy. To burn the iso file:

Along your menu bar, go to Applications > Sound And Video > Brasero

Using Brasero you can burn CD's / DVD's etc... You want to select the "Burn An Image" option and browse to where you downloaded the iso file.

Once done, you need to pop the CD in the drive, and boot from it. I'll download it too, just so I can run through it (as I've got an older version) in case you need help with the steps. It should be quite straight forward though, it typically highlights/selects the right option for you.
