1. Via Synaptic Package Manager
Akses Synaptic Manager:
System --> Administration --> Synaptic Package Manager
Search dengan keyword 'kernel', lalu hapus kernel lama yg anda inginkan. Tapi, penting untuk diingat!, jangan salah hapus kernel yang sedang anda gunakan.. hehehe..
Untuk mengetahui kernel yang sedang digunakan, ketikkan perintah:
# uname -a
Contoh:
root@spydeeyk-r00m:~# uname -a
Linux spydeeyk-r00m 2.6.32-30-generic #59-Ubuntu SMP Tue Mar 1 21:30:21 UTC 2011 i686 GNU/Linux
Nah, pada contoh diatas kernel yang saya gunakan 2.6.32-30-generic.
Oh ya, setelah kernel lama dihapus alias diremove via synaptic package manager lakukan pula perintah:
# update-grub2
2. Via Command Terminal
Pertama kita cari tahu dahulu kernel-kernel yang terinstall di system kita dengan perintah:
root@spydeeyk-r00m:~# aptitude search linux-image-2.6 | grep "i "
Contoh:
root@spydeeyk-r00m:~# aptitude search linux-image-2.6 | grep "i "
i linux-image-2.6.32-21-generic - Linux kernel image for version 2.6.32 on x
i linux-image-2.6.32-22-generic - Linux kernel image for version 2.6.32 on x
i linux-image-2.6.32-24-generic - Linux kernel image for version 2.6.32 on x
i linux-image-2.6.32-29-generic - Linux kernel image for version 2.6.32 on x
i linux-image-2.6.32-30-generic - Linux kernel image for version 2.6.32 on x
Setelah mengetahui kernel-kernel yang terinstall, sekarang kita bisa remove kernel yang kita inginkan (ingat jangan remove kernel yang sedang dipakai, ok? :D )
Contoh:
root@spydeeyk-r00m:~# aptitude purge linux-image-2.6.32-21-generic

That's it.. :)
Bagi saya ada baiknya disisakan 2 kernel.. kernel yang sedang dipakai dan sebelumnya, buat jaga-jaga aja.. :D
