When I turn on my machine it takes longer loading the grub boot menu then the OS i.e. a long time. I also wish to edit my menu.lst but I can't find it. As far as I know it shoud always be /boot/grub/menu.lst
Grub is installed on sda
/boot sdb1 ext4 165MB used
/ sda1 ext4 raid 0
/ sdb3 ext4 raid 0

As you can see there is alot of stuff there, I don't think it is normally. Do other people have this many files there.

What version of kubuntu are you running? So far as I know, 9.10 runs grub 2, which is alot different. If you are running an earlier kubuntu, I dunno what you did to your /boot directory!

Okay there is half my answer.I didn't know there was a grub2. I am using Karmic Koala. So I'm now thinking that it is a problem with grub2. There is a bug in grub2 which makes booting from the drive that doesn't have /boot on it makes it really slow. To fix that you can install grub2 on the drive that has /boot on it. sudo dkpg-reconfigure grub-pc

Instead of /boot/grub/menu.lst you can edit /boot/grub/grub.cfg. Apparently your not meant to edit this file but I did any way and everything is fine.
sudo cp -a /boot/grub/grub.cfg /boot/grub/grub.cfg.backup
sudo vim /boot/grub/grub.cfg
Edit
:wq! to save

You should read this: https://help.ubuntu.com/community/Grub2, there is good reason not to modify the /boot/grub/grub.cfg file. Simply put, your mods will be overwritten every time you update grub!

Yes I know that but I am not planning on updating grub. If I install or update something I will manually edit the file.

Fair enough. I still think you should try using it the way it's meant to be used, but it's your call.
