Ubuntu Server Booting Woes
Be gentle, i'm a complete beginner.
Ive installed Ubuntu Server 11.4 on a newly built computer. The installation has gone OK however, the computer hangs on boot at "Loading Operating System" (It has worked on a previous install, but will not work now after 3 attempts).
I have burnt Supergrub to a CD, booted from it and successfully booted the Ubuntu install. I then installed ununtu-desktop, all the updates and rebooted. Computer still hangs on "Loading Operating System" so again, booted from Supergrub CD.
How do I get this to boot without having to use the Supergrub CD?

Hmmm not sure about that one, I'd stick the Ubuntu disk in and see if there's a repair option - or re-install it.

When you use the Supergrub cd what option are you using that boots the server correctly?
What hardware setup do you have? (Has it written the grub loader to somewhere silly so that it is unbootable? - Scsi drives without drivers installed etc?)

@cpjitservices: I've installed 3 times now and changed hard drive.
@siuko: Supergrub options:
1. Select any OS
Then the choices are:
Linux 2.6.35-22-generic pae
Linux 2.6.35-22-generic pae (Single-user mode)
Linux 2.6.35-24-generic pae
Linux 2.6.35-24-generic pae (Single-user mode)
First boot only Linux 2.6.35-22 option available, I booted from this, installed ubuntu-desktop & all available updates & rebooted. Now choice of Linux 2.6.35-22/24 boots fine from either.
Drives comprise of 1 x DVD, 1 x 40gb IDE for OS & 6 x 2tb SATA for storage.

try adding 'apci=off' to your grub when it boots.
when grub loads you press 'e' i bleieve to go into edit mode and then add to the end of the line and follow the onscreen instructions to boot it

Did you install from USB by any chance? I found that Ubuntu could be a bit daft with USB installs and write grub to the USB rather than your master HDD. Booting from the Ubuntu disk in to command line repair mode will allow you to re-install grub to the correct HDD.
This guide is meant for reinstalling grub after windows removes it, but the same steps apply (first section only):

So, I boot from Supergrub CD, and then press "e"? If so, I get:
GRU GRUB version 1.90
Then a box which contains:
Underneath the box is:
Minimum Emacs-like screen editing is supported. TAB lists
completions. Press Ctrl-x to boot. Ctrl-c for a command-line or ESC
to return menu.
Do I make configfile $script_prefix/osdetect.lua configfile $script_prefix/osdetect.lua apci=off

no sorry by bad - you need to add the line to grub when booting from the server. If you can't get to grub on the server then best bet is to do as Los0jos suggests and reinstall grub

It was a fresh install from a downloaded .iso. I have tried 2 hard disks and 2 freshly burnt CD's up to now with the same results. As I'm not running a dual boot system, is there any point in following the link you provided?

Ahh. Grub wont load, just:

It's worth a try as grub by default handles the initial loading of the operating system, if it's setup has somehow become corrupted that could be causing your problem. You have nothing to lose (so long as you have backups, ALWAYS have backups!)

I'm probably being slightly dumb here..............
I've booted from the Ubuntu Server CD, couldn't find an option for terminal, so...................
I booted from the Supergrub CD into Ubuntu Server, opened a terminal and typed "sudo grub"
Returned sudo: grub: Command not found............Bug**er
Further help required, can I edit GRUB directly now i'm in the OS?

If you're in the OS then you should be able to run the necessary commands from that article in a terminal window
7th January 2011, 03:16 PM #14
When typing "sudo grub" in terminal (as per the link you sent me) I receive:
sudo: grub: command not found
7th January 2011, 03:18 PM #15
That suggests to me then that grub isn't installed on your machine; did you specifically choose to use an alternative boot loader when you installed the OS?
