Pengalaman berpindah dari Lilo ke Grub (quick and dirty)
Alasan :
– Saya membutuhkan memuat beragam system operasi dalam PC saya, karena tuntutan pekerjaan. Dengan adanya beragam
System Operasi dalam PC saya maka hal tersebut menuntut bootloader yang bisa meload beragam OS dalam HD saya
tersebut. Dalam beberapa hal, saya menyukai LILO. Namun keterbasan LILO dalam menangani kondisi yang saya
harapkan membuat saya harus memikirkan bootloader lain. Salah satu bootloader lain yang saya kenal adalah
GRUB (GRand Unified Bootloader).
Pendahuluan :
hda1 –> Windows 2000
hda2 –> Slackware 8.1
hda3 –> Debian Woody 3.0
hda5 –> Linux Mandrake 8.2
Berikut output dari cfdisk :
cfdisk 2.11n
Disk Drive: /dev/hda
Size: 10005037056 bytes
Heads: 255 Sectors per Track: 63 Cylinders: 1216
Name Flags Part Type FS Type [Label] Size (MB)
————————————————————————————————————-
hda1 Primary Win95 FAT32 3676.71
hda2 Primary Linux ext2 1497.01
hda3 Boot Primary Linux ext2 1497.01
hda5 Logical Linux ext2 1497.01
hda6 Logical Linux swap 386.59
hda7 Logical Win95 FAT32 1447.65
– Setelah utek-utek sebentar, akhirnya saya temukan quick and dirty dalam implementasi GRUB.
1. Mother OS tempat GRUB Dikontrol
===================================
– Saya memilih debian sebagai ‘mother OS’ untuk memanaje grub, dimana dari tabel partisi HD saya terletak di hda3.
(Fans baru debian, rek…! 😀 )
Kemudian mencari paket grub :
buraq:~# apt-cache search grub
grub – GRand Unified Bootloader
Instal pake grub :
apt-get -y install grub
Atau dalam redhat dan mandrake :
rpm -Uvh /path-ke-dir-RPMS-dalam-redhat-atau-mandrake/RPMS/grub******
Cek apakah dir /boot/grub sudah ada atau belum, bila belum maka kita buat :
buraq:~# mkdir /boot/grub/
buraq:~# cp /usr/lib/grub/i386-pc/stage1 /boot/grub/
buraq:~# cp /usr/lib/grub/i386-pc/stage2 /boot/grub/
buraq:~# cp /usr/lib/grub/i386-pc/stage2 /boot/grub/
buraq:~# cp /usr/lib/grub/i386-pc/e2fs_stage1_5 /boot/grub/
Test grub :
buraq:~# grub
Probing devices to guess BIOS drives. This may take a long time.
GRUB version 0.91 (640K lower / 3072K upper memory)
[ Minimal BASH-like line editing is supported. For the first word, TAB
lists possible command completions. Anywhere else TAB lists the possible
completions of a device/filename. ]
grub> root (hd0, <– ketik [TAB disini]
Possible partitions are:
Partition num: 0, Filesystem type is fat, partition type 0xb
Partition num: 1, Filesystem type is ext2fs, partition type 0x83
Partition num: 2, Filesystem type is ext2fs, partition type 0x83
Partition num: 4, Filesystem type is ext2fs, partition type 0x83
Partition num: 5, Filesystem type unknown, partition type 0x82
Partition num: 6, Filesystem type is fat, partition type 0xb
grub> root (hd0,
Sedikit bingung ?
begini konversinya : cfdisk membaca dari angka 1 sedangkan grub dari 0
Sehingga (cek dengan output cfdisk saya):
hda1 –> Partition num: 0, Filesystem type is fat, partition type 0xb
hda2 –> Partition num: 1, Filesystem type is ext2fs, partition type 0x83
…dst
2. Setting Up GRUB
======================================================
Sekarang hapus ketikan anda di grub sheel dan ketik :
grub> quit
Pindah ke /boot/grub
buraq:~# cd /boot/grub/
Buat file yang berisi daftar yang ingin di load
buraq:/boot/grub# vi menu.lst
#———————-start file—————————-

initrd (hd0,4)/boot/initrd.img

Akan memberikan efek seperti kita mengetikkan :
LILO: linux -s
Kemudian simpan file /boot/grub/menu.lst
3. Menuliskan GRUB ke MBR menggantikan LILO
=============================================
Masuk ke dalam shell grub :
buraq:/boot/grub# grub

GRUB version 0.91 (640K lower / 3072K upper memory)
[ Minimal BASH-like line editing is supported. For the first word, TAB

completions of a device/filename. ]
grub> root (hd0, <<– ketik [TAB]
Possible partitions are:
Partition num: 0, Filesystem type is fat, partition type 0xb
Partition num: 1, Filesystem type is ext2fs, partition type 0x83

Partition num: 4, Filesystem type is ext2fs, partition type 0x83
Partition num: 5, Filesystem type unknown, partition type 0x82
Partition num: 6, Filesystem type is fat, partition type 0xb
grub> root (hd0,2)
Filesystem type is ext2fs, partition type 0x83
grub> setup (hd0)
Checking if “/boot/grub/stage1” exists… yes
Checking if “/boot/grub/stage2” exists… yes
Checking if “/boot/grub/e2fs_stage1_5” exists… yes
Running “embed /boot/grub/e2fs_stage1_5 (hd0)”… 16 sectors are embedded.
succeeded
Running “install /boot/grub/stage1 d (hd0) (hd0)1+16 p (hd0,2)/boot/grub/stage
2 /boot/grub/menu.lst”… succeeded
Done.
grub> quit
OK selesai setting Up GRUB. Silahkan reboot PC anda dan voila…. GRUB anda telah berjalan
