i think you should just edit the grub.conf file

ok....how do i do it?

Use synaptic to remove the kernel(s) you do not want.
You may then need to run sudo update-grub
Most people prefer to keep at least one ("fallback") kernel version.

what is synaptic and how do i use it?

Open a console in gui and type 'synaptic' after you have logged in as the root... else go to administation -> package manager -> synaptic. Did you explore the gui atleast?
Comeon, it is the same program/interface with which you downloaded the kernels to begin with.

Code:

sudo cp /boot/grub/grub.conf /boot/grub/grub.conf-bak
sudo gedit /boot/grub/grub.conf

and comment out any line beginning with title.

That file is not meant to be edited, it is autogenerated and all changes will be discarded the next time any update issues the comnmand update-grub. The correct way to get rid of the entries is in fact to remove the old kernels.

By the way, in Ubuntu the file is named grub.cfg.

right i removed the kernals but the options are still there, thats the only thing that bothered me.my biggest concern is geting python 3. so far i have found 2 different ones and i dont know what they do or which one is correct. i found sudo apt-get install python3 and sudo apt-get install python 3.1.3

the first one is a 12 mb file and the second it 500+ mb which one is correct? i tried installing both but one of them keeps crashing the computer and i dont know which one

Easy, Tiger... With Ubuntu, kernel updates are issued automatically through the Update Manager.

The *easy* way to remove the menu options is to install Startup Manager from the Software Center. It allows you, among many other things, to choose how many boot options are available at startup.

As for the Python issue- Ubuntu is not the best distro for manually installing software outside of the repositories. That would be Slackware, Debian, or Gentoo, but get ready for a different ride.

Cheers

I downloaded it but there isn't and option to remove boot options. I'm a little lost...

If they've been removed try:
update-grub
or
sudo update-grub

Grub should not see so it shouldn't list them.

for your python question

Code:

sudo apt-get install python3

Or use Synaptic or the Software manager and look for python3
