[ltp] Partition problems?

[D. Sen]

Here are the instructions from the march issue of Linux Gazette
(http://www.linuxgazette.com):

Step 2: Installing GRUB

Installing GRUB can be broken into three separate parts:

  1.Installation of "stage1" in MBR.
  2.Setting up the address or location, "stage2".
  3.Setting up a boot menu or set of options to choose which operating oystem
to boot.

Start installing GRUB by issuing the following command:

[root@heaven /boot/grub ]# ./grub

This command probes devices to guess BIOS drives and produces an output
message. This may take a long time.

end_request: I/O error, dev 02:00 (floppy), sector 0

    GRUB  version 0.5.96.1  (640K lower / 3072K upper memory)

NOTE: Although it may seem surprising, GRUB does have 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. You may be surprised to see this feature.
Something like this then appears:

grub>

Now, I assume that you have installed your Linux distro in the first extended
partition in the first disk or /dev/hda5. Remember the GRUB
naming convention and rename the above to (hd0,4). Type the following command:

grub> install (hd0,4)/boot/grub/stage1 (hd0) (hd0,4)/boot/grub/stage2 p
(hd0,4)/boot/grub/menu.conf

Now let's examine this command in detail:

install
      a built-in command that tells GRUB to install
(hd0,4)/boot/grub/grub/stage1 to (hd0), the Master Boot Record.
(hd0,4)/boot/grub/stage2
      tells grub where the stage2 image is located.
p with the the following options: (hd0,4)/boot/grub/menu.conf
      sets the configuration file for displaying nice menus. I will later
discuss the structure of the configuration file.

We can also summarize that command as follows:

  1.install
  2.source_of_stage1
  3.where_to_install
  4.source_of_stage2
  5.p source_of_configuration_file

You have now completed the basic hard drive installation.
