[SOLVED] Safe to uninstall old kernels?

[Fernanddo Saenz]

Hello,
I have a Dell Vostro 1000 laptop running 8.04 (dual boot with XP). My grub menu has grown a bit long now, since it has all kernels since 2.6.24-16, including -18, -19, -21 and now runs 2.6.24-22. Question is: Can I safely uninstall everything related to kernels -16, -18, -19 without thrashing anything? I'd like to keep just the previous kernel, besides the current. Counting the linux-headers, generic kernel, restricted modules, etc., they're taking up 515MB. I'd like to clean up a bit since I have only 40GB for Ubuntu
Thanks

...indeed it is safe, as long as you need not boot to the old ones.

You can uninstall the old ones using synaptic. Next, clean up grub

gksudo gedit /boot/grub/menu.lst

edit kernel options line:


## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=1

Then

sudo update-grub

The old entries should be gone.
