The duplicate rows are different kernel rows... for the same Ubuntu 8.04 system....
You can remove old kernel... and the rows will disappear...

Open a Terminal from the menu Applications->Accessories->Terminal copy and paste here the result of this command copy and paste it into terminal:

dpkg -l | grep -i linux-image

Thank you

This is what i get when running the command:
ii linux-image-2.6.22-14-generic 2.6.22-14.52 Linux kernel image for version 2.6.22 on x86
ii linux-image-2.6.24-16-generic 2.6.24-16.30 Linux kernel image for version 2.6.24 on x86
ii linux-image-2.6.24-17-generic 2.6.24-17.31 Linux kernel image for version 2.6.24 on x86
ii linux-image-generic 2.6.24.17.19 Generic Linux kernel image

How do I remove old kernels then?

Why do you want to get rid of them? They can be useful if your kernel gets screwy (admittedly a rare event). If grub is taking to long to boot, go to Applications->Add/remove and look for a "start-up manager". Its icon is a wrench with a red handle oriented like a \ and there are two of it in the list (don't ask why, I have no idea). You can adjust the time you have to wait before Grub will boot with default options like this:
System->Administration->StartUp Manager->Use timeout in bootloader menu. So, is there really a reason for getting rid of them? If so, you can (from the startup manager) go to the advanced tab and limit/adjust the number of kernels to keep.

Thnx guys.. I didnt know tht having a few kernels are necessary.. I just don't like it to be cluttered, thts all. I guess I'll just keep it that way, then. Thanks again :D
