GRUB Legacy: Difference between revisions

GRUB will boot into its command shell. (If your system does boot from hard drive instead, check your BIOS boot drive settings.) When the <code>grub ></code> prompt appears, remove the auxiliary disk from the drive and replace the boot disk. From the GRUB shell, you can now complete the installation on the boot disk:

 

install (fd0)/boot/stage1 (fd0) (fd0)/boot/stage2 (fd0)/boot/menu.cfg

 

The parameters tell GRUB:

If you need to mount your USB device: (Exchange <code>sdb1</code> with your device name.)

 

mkdir /mnt/sdb1

mount /dev/sdb1 /mnt/sdb1

 

Create required directories:

 

mkdir /mnt/sdb1/boot

mkdir /mnt/sdb1/boot/grub

 

Locate the <code>stage1</code>, <code>stage2</code>, and <code>*_stage1_5</code> files:

 

find / -name stage1

 

Copy stage1 and stage2 files, <code>/usr/lib/grub/</code> is an example location, use the location returned by the find command:

 

cp /usr/lib/grub/stage1 /mnt/sdb1/boot/grub/stage1

cp /usr/lib/grub/stage2 /mnt/sdb1/boot/grub/stage2

 

For FAT formatted USB device use:

 

cp /usr/lib/grub/fat_stage1_5 /mnt/sdb1/boot/grub/fat_stage1_5

 

For ext2 formatted USB device use:

 

cp /usr/lib/grub/e2fs_stage_1_5 /mnt/sdb1/boot/grub/e2fs_stage_1_5

 

Then execute the GRUB install application:

 

sudo grub

 

Enter the following commands:

 

root (hd1,1)

setup (hd1)

quit

if you don't know where your kernel is, you can use the command "find /boot/grub/e2fs_stage_1_5" to get the parameters which would be used in the command root (sdb1,1) and setup (sdb1).

 

Run

 

./configure --help

 

to see a list of options. In my case, I use Netgear tulip cards, so I execute:

 

./configure --enable-tulip

make

make install

 

You may want to consider using the <code>--prefix</code> option if you don't want to overwrite your existing GRUB install or do not have root access.
