I managed to get VB working in the end. Still no AVG though.

There is no bug. I have Virtualbox installed and in the menu. I do not use
AVG so can't comment on that. You may have to re-install AVG.

Virtualbox may not have installed properly for you. You need to have certain
build utilities installed. In Ubuntu, install build-essential. It contains
the necessary build applications that are required not for Virtualbox to
run, but to compile the kernel module. This is one of the times that running
from the commandline is better. It would have shown you the message, rather
than leave you hanging. The Virtualbox module loads when you boot up. When
you start Virtualbox from the menu. It will load the interface.

Once you have the necessary compilers installed, run virtualbox from the
commandline and it will show you the error and tell you what commnad to type
in. I forget the name and path. I think that it is virtualbox-config or some
such thing. Anyway, it should finish the installation once you run it.

If you think that this is a pain then you should try to install VMWare.

There is one other trick to get Virtualbox running properly. You need to add
yourself to the vboxusers group in the System, Administration, Users and
Groups.

After installing the gui for grubit appeared in the Applications/System tools,
section. Grub wouldnt work however it says on the icon "choose next default for
grub" bu nothing happens when i click on the icon, so what gives, this is the
third error from the Ubuntu menu system. these instructions for installing grub
didnt work for me, i have installed Linux Ubuntu 64 onto another partition, but
during its installatin it didnt ammend the Grub so that i could choose betwen
32/64 and XP, what can I do besides whats in the video?

I tried to reinstal the Grub both from 32bit Ubuntu and the 64bit live CD.

Grub is a bootloader. It is not meant to work from the menu. Grub is used
only when you re-boot and displays briefly so that you can choose which OS
to boot.

The problem isn't with the Ubuntu menu, but with your expectations and lack
of understanding.

Some things will never display in the menu, They are not meant to be used
from a menu. In the case of Virtualbox it was because of an installation
problem. In the case of Grub it is a bootloader and only can run when you
boot. You can edit Grub using various applications but you cannot run it.

You are assuming too much and the worst thing is that you are assuming
something is broken when it isn't. Instead think that if something is not
working it is for a valid reason and then try to find the reason. Helping
someone when you can't see their computer, what they've done or what they
haven't done is difficult enough. Adding to the difficulty by trying to do
things that no Linux user would do is and jumping to conclusions makes it
next to impossible.

As for Grub itself what is not happening that you want to happen? You can
edit grub quite easily with any text editor. You can change the drive,
partition, parameters and default boot order. seldom you need to rewrite
Grub unless it has been written over by Windows or is on the wrong drive.

I never meant to 'run' grub, my post has been about running a reinstall to
replace it with an appropriate setup.

Anyway, I've now got too many menu items in grub as it is showing new and old
kernels to choose from (i used the 64bit disk to go through the re installation
process of linux but without the format partition option ticked, it eventually
reinstalled packages and then got to the bootloader part, luckily I didnt have
enough use of 64bit install to make it a complete waste of time in instaling and
configuring it how I want it to be(assuming the reinstall wold remove user
settings)) , I am aware of the file to edit in the boot/grub folder, however, I
wanted to very quickly change things and not have to spend the afternoon reading
a manual on how the file is setup, the fact that not all Linux distros have
simple to use GUI interfaces for some of the most important yet simple features
is what is keeping windows users out and somehow suggests to me linux developers
dont want more people using linux, just how many thousands of posts of requests
for grub GUI interface must there be? I saw these ten years ago... I made some!
I have spent many hours this week using and learning new things about ubuntu, I
followed the instructions on how to reinstall the grub exactly, and it didnt
work.

Just on a cautionary note: do make sure the instructions you followed were
for your version of grub if you are still trying to resolve booting into the
64bit version. If you used version 9.1 or higher of Ubuntu, there is now
Grub2, which is different than the grub in the video I think. Try searching
for "fix grub2 after install" or "fix grub after install" for more info in
google. I havent had to do that yet, so I do not know the specifics or
which resource is the best, though I would think this is best done by
editing the grub config file then running "sudo update-grub".

There are utilities that remove old kernels. Computer Janitor can do it as
can Ubuntu Tweak from Getdeb.net. You can also remove them with Synaptic.
When you remove the old kernels it removes the lines from grub for you. If
you only edit grub then you still have the kernels installed.
