No Recovery mode on Grub list

[mistrynitesh]

I just now installed Elive Gem on my computer which already had WinXP and Kubuntu (Kubuntu was installed WinXP). During installation of Elive, it asked me to select a location for Grub, with the options being
1. MBR on /dev/hda
2. Boot location (Grub would be installed on the Elive partition); and
3. Do not install Grub (Elive won't boot)

I selected the first option (MBR, thinking it would be wise) and went ahead.
Installation went fine. However, on reboot, the Grub installed by Elive appeared with other options being WinXP, Ubuntu 2.6.20.16 and Ubuntu 2.6.20.15 (as I had upgraded the kernel earlier). The difference being that, before Elive installation, I used to get two more options i.e., recovery modes for both the versions of Ubuntu. They have disappeared now. The system is running fine.
Should I be concerned that the options have disappeared? If so, Is there any way to bring back the same?

Don't worry - recovery mode is just boot with options: ro single.

If you want, you could add those options in the Elive Gem menu.lst.
Look at ubuntu /boot/grub/menu.lst and Elive Gem /boot/grub/menu.lst. Copy recovery parts from ubuntu to the Elive (syntax ! feisty is using UUID).

Note
If you upgrade Feisty to the Gutsy or there is kernel update (2.6.20.17 or something) then you also need to edit Elive's menu.lst.

Afterthoughts :

ro = Mounts the root filesystem read-only.
single = Starts Linux in single-user mode.

Myself, I would have chosen #2 or#3 so as not to effect previous installations. You could then have edited your /boot/grub/menu.lst to reflect the Elive installation and have the choice to boot it on power up. Just a preference.

After learning how to edit the grub menu list, even I think 3rd option would have been safer (What if the new grub wouldn't have been installed properly?).
Anyways, as a saying goes in Hindi:
"Subah ka bhoola agar shaam ko ghar aa jaaye to use bhoola nahin kehte"
(meaning "If a mislead returns home by the evening, then he cannot be called mislead")

#3 would not have worked because if grub is not installed no bootloader would have found it and you would had have to install grub to your elive partition.

Then the "misslead" would not have come home and really be mislead

Re: No Recovery mode on Grub list

You can move grub pointing to the Kubuntu and add Elive to the Kubuntu menu.lst


Example: Making grub to start kubuntu from sda1

In the konsole:

:~$ sudo grub

Checking where is /boot/grub/stage1

grub> find /boot/grub/stage1
(hd1,0)
(hd2,0)

Moving grub to start from partition (hd2,0)

grub>root (hd2,0)
Filesystem type is ext2fs, partition type 0x83

This will install the GRUB boot loader on the Master Boot Record (MBR) of the first drive.

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 (hd2,0)/boot/grub/stage
2 /boot/grub/menu.lst"... succeeded
Done.

When everything is ready:

grub>quit
