View Full Version : [SOLVED] 12.04 Install Errors

Hello Everyone, I am having a issue installing Ubuntu 12.04 onto my desktop. When it boots normally to install Ubuntu I get this screen:

http://tinypic.com/r/300bc3o/6

I looked around and found some info that told me to turn off noapic before booting so I did and tried installing again. After a black screen with a blinking line, I come to the Ubuntu loading screen (I assume it's trying to install). After a couple of minutes, I run into this screen and this is where I can't find any useful information that works:

If anyone can help me out, I would greatly appreciate it a lot.

Thank in advance!

I don't know what is happening, but if you check some things and answer some questions, I or someone else might be able to help to find out what to do.

It seems not to find /dev/sr0 at some stage, while it obviously found it earlier.

- Are you trying to install from CD or USB?

- How did you make your installation drive?

- Did you try to run Ubuntu live (not installing, only testing)?

- How many primary partitions are there on your internal hard disk drive?

- Please post the output of these commands (if possible to run Ubuntu live)

sudo fdisk -lu

df

I believe you have a faulty ISO or burned your disk wrong. So, with the possibility in mind that your ISO is wrong, I would suggest downloading it again and check it with an md5sum hash (you can find some info about what it is and how to do it here (https://help.ubuntu.com/community/HowToMD5SUM)) and then try to burn the disk again. If you just do that I can bet it will work (that unless you have some faulty hardware piece, which is not that much likely) and you will have a functioning Live (CD? DVD? USB?)

Thank you for the move!

- Installing from CD
- I burned the CD from my main desktop (Did I understand your question correctly?)
- Tried running live, same issues as trying to install.
- There should only be one partition. I cleared the other partition when installing XP until I can get Ubuntu as my primary system.
- Sorry, can not even get the live to run. I have been able to install 10.10 along side of Windows but still have boot issues with apic.

I have downloaded and installed 12.04 and 10.10, same issues. I have checked the md5sum hash and they are the same for 12.04 (Thank you for the md5sum link). I also burned the CD at the lowest speed I can which is 4x.

Try this thread (http://ubuntuforums.org/showthread.php?t=1646473) for when to run the command and what to do after install with Grub boot configs (https://help.ubuntu.com/community/Grub2).

Thank you. This should at least help me in the short term. However, my ultimate goal is to be able to install ubuntu as my only OS on this pc. Unfortunately, I have only been able to install ubuntu as a second OS via XP. So I need to find out why I am getting that other issue.

Did you have any success with jtarin's suggestions?

You have a wubi installation of Ubuntu now. There is room for Ubuntu in the partition table.

But first you should spend some time to get Ubuntu running when booting a live session from the CD. Set the BIOS to boot from CD if there is one. Reboot with the CD inserted!

You should try several boot options, not only noapic, but also acpi=off and above all nomodeset. Try combinations of them (for example all three). See the following link, which explains how to do when trying Ubuntu from a CD without installing.
https://help.ubuntu.com/community/BootOptions (https://help.ubuntu.com/community/BootOptions)

Please come back and tell us about your results before continuing :-)

-o-

If still no go, please post the specs of your computer:

- cpu, ram and graphics card

If successful from live, you can then use those boot options in your installed system according to the following link.
http://ubuntuforums.org/showthread.php?t=1195275 (http://ubuntuforums.org/showthread.php?t=1195275)
Read section 5 about boot options, particularly about


GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
This line imports any entries to the end of the 'linux' line (Grub Legacy's "kernel" line). The entries are appended to the end of the normal mode only. This is similar to the "defoptions" line in menu.lst. For a black screen with boot processes displayed in text, remove "quiet splash". To see the grub splash image plus a condensed text output, use "splash". This line is where other instructions, such as "acpi=off" are placed.


GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
can be changed to for example

GRUB_CMDLINE_LINUX_DEFAULT="nomodeset noapic acpi=off" during debugging and finally to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset noapic acpi=off"

Remember to run
sudo update-grub before rebooting to activate these changes.

Hey there Sudodus, I booted my disk and went to "Try without installing" with noapic, acpi=off, and nomodeset turned off. It loaded up without any issues :). Should I do this again and try installing this time or is there something I should do first?

I thank you guys for all of the help thus far. It really means a lot.

0. Check also if you need all three boot options. For example try without acpi=off! Use as few options as possible for your installed system!

1. I recommend strongly that you backup your system now, or at least all your private files: documents, pictures, video clips, music that you want to keep. Because editing partitions is risky.

2. Decide if you want to keep Windows and have dual boot, or if you want an Ubuntu-only system. A dual boot system is better than wubi. You will get the full power and stability of Ubuntu as well as Windows.

3. If you want to keep Windows, boot into Windows and

- uninstall wubi and/or ubuntu and make sure the big file containing the Ubuntu file system is deleted.

- delete all other unnecessary files (trashcan, cache, etc)

- defragment the Windows partition.

4. If you want to keep Windows: To increase visibility (so that you know what you are doing) I suggest that you edit the partitions with gparted during a live session booted from the Ubuntu install disk.

You used 25 GB for wubi, and it is reasonable to shrink /dev/sda1 so that there can be room for an extended partition of 30 GB.

In that extended partition, create two logical partitions, one swap partition a little bigger than your RAM (in Gibibytes) if you want hibernation, otherwise only 1 GB, and the rest of the free space should be a partition formatted with ext4.

5. Install booted from the CD. When asked about partitioning, select something else, select the ext4 partition for your root file system (/), and select the drive /dev/sda (not a partition /dev/sda1, /dev/sda5, /dev/sda6 ...). The swap will be selected automatically. You need not format anything now, if you did it with gparted before.

--o--

If you want to skip Windows, you can select a simple option, to use the whole drive for Ubuntu and let the installer do all the partitioning and formatting.

--o--

Finally you need to edit the line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" according to the instruction in post #9 and run
sudo update grub and reboot.

Hey,

I kinda jumped the gun and went on to installing. I had no intentions on keeping windows and had no files I needed to keep so I completely wiped everything and am in the process of installing Ubuntu 12.04 as the OS. Once it has finish, I can used the tips you guys have provided me about the boot settings to make sure I boot smoothly into the OS after installation.
