Cannot boot with Grub 2 (continuation)

Asked by Asta Lyberth

First a Big THANK YOU for being available to help day and night, without me/us having to 'order a time' for consultation, make an agreement, or anything like that!!! Through my mind I give YOU a BIG hug for that!

Problem:

- Have just installed GRUB 2 with synaptic.
- Was in this context told to write 'upgrade-from-grub-legacy' as root if prompted for anything in this regard.
- When rebooting and prompted, I wrote 'sudo upgrade-from-grub-legacy'
- but the rebooting did not proceed to the next step whatever line or command letter I entered /wrote. Instead it returned to the highlightened line again and again.

? Can I reverse this installation action and get back to the former bootloader?

I thank you again for this invaluable possibility to get help and support in this way!

Why I installed GRUB 2?

I was looking for something that might be able to update a too slow usb mass storage device and typed 'update' in synaptic with this 'unknown' thing connected to the comp. There this Grub 2 emerged and was compared with the original Grub which come to sound somewhat primitive against it. This, on the other hand, would update itself (leaving me the uncomfortable thought that I had to update the original) which together with a very short 'what to do if' made me decide to replace the original with this easy, selfupdatingGrub 2 so superior to the original...

- When I type 'sudo -s' in the terminal on this Live CD, this happens:

ubuntu@ubuntu:~$ sudo -s
root@ubuntu:~# root
The program 'root' is currently not installed.  You can install it by typing:
apt-get install root-system-bin
You will have to enable the component called 'universe'
bash: root: command not found
root@ubuntu:~#

- Where do I enable this component 'universe'?

Thank you for your patience!

Asta

You don't need to. root is not program, its an ccount. by running sudo -s you have gined a root shell. A better option is:

sudo -i

as all the settings will be from your users home folder and not /root

Using a different bootloader will never speed up the access to a storage device. That simply makes no sense at all. I think you should look at what grub2 actually does before persuing grub2

From: http://www.gnu.org/software/grub/grub-2.en.html

GRUB 2 targets at the following goals:

    * Scripting support, such as conditionals, loops, variables and functions.
    * Graphical interface.
    * Dynamic loading of modules in order to extend itself at the run time rather than at the build time.
    * Portability for various architectures.
    * Internationalization. This includes support for non-ASCII character code, message catalogs like gettext, fonts, graphics console, and so on.
    * Real memory management, to make GNU GRUB more extensible.
    * Modular, hierarchical, object-oriented framework for file systems, files, devices, drives, terminals, commands, partition tables and OS loaders.
    * Cross-platform installation which allows for installing GRUB from a different architecture.
    * Rescue mode saves unbootable cases. Stage 1.5 was eliminated.
    * Fix design mistakes in GRUB Legacy, which could not be solved for backward-compatibility, such as the way of numbering partitions.

At no point does it mention speed. USB is slow compared to internal PATA / SATA disks so the slowness is expected.
