Just installed Ubuntu, and there is no option to boot it.

[rilomuse]

Running it from the disc right now all fine and dandy.

I managed to use that script that helps identify these problems. I think that I managed it correctly.

[lisati]

To boot into Ubuntu, all that is usually needed is to restart your computer, remembering to take the CD out when requested.

[rilomuse]

Oh, yes... I've done that a few times.

It just sits at some screen for a few minutes then asks me to pick to boot my CD drive or my Hard Drive first. Then if I boot the hard drive that I installed Ubuntu, too.. It sits at that same screen.

[23dornot23d]

Will just add the output here for you more people may comment on it ....

:( Oh, sorry, new here so wasn't sure how to post it.

[darkod]

You have identical situation like here:
http://ubuntuforums.org/showthread.php?t=1926948

Look at my post #9. That might help you point you in a right direction.

[rilomuse]

Thanks, I'll try and figure out what this means then... Thanks! I'll see if any of this helps.

EDIT: Eh.. Didn't really figure anything out. It's all just gibberish to me <_< Was hoping I just needed to install a little something or other.

Last time I installed Ubuntu a few years ago, it just installed perfectly fine and booted right up...

[23dornot23d]

I pm'd drs305 as he is a wizard on these things .....

this is the response ..... hope it helps ....



You must install grub to the MBR. To do so, boot the 11.10 LiveCD, mount your Ubuntu partition and install Grub:

Code:
sudo mount /dev/sda2 /mnt
sudo grub-install --root-directory=/mnt /dev/sda

Don't use the partition number in the second command.
Reboot without the LiveCD.


drs305

[rilomuse]

K, I'll try that. I just paste that code into the terminal, right?

[23dornot23d]

Wait - there may be more to this than that with it being EFI .......

/dev/sda1 34 39,096 39,063 EFI System partition

# /boot/efi was on /dev/sda1 during installation UUID=CCD4-B726 /boot/efi vfat defaults 0 1


http://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface (http://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface)

[drs305]

Sorry, I failed to notice the EFI portion of RESULTS.txt

I don't think it's going to be as simple as I expected, since you are using EFI. I haven't used it so I think you will have to wait for someone who does if you want to use EFI. (Although I agree with darkod in the post he references.

[rilomuse]

I apologize again, this is what I got...


mount: unrecognized option '--root-directory=/mnt'
Usage: mount -V : print version
mount -h : print this help
mount : list mounted filesystems
mount -l : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
mount -a [-t|-O] ... : mount all stuff from /etc/fstab
mount device : mount device at the known place
mount directory : mount known device here
mount -t type dev dir : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
mount --bind olddir newdir
or move a subtree:
mount --move olddir newdir
One can change the type of mount containing the directory dir:
mount --make-shared dir
mount --make-slave dir
mount --make-private dir
mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
mount --make-rshared dir
mount --make-rslave dir
mount --make-rprivate dir
mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using -L label or by uuid, using -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say man 8 mount .

[darkod]

Note that those are two separate commands to run one after the other.
sudo mount /dev/sda2 /mnt
sudo grub-install --root-directory=/mnt /dev/sda

I wonder if that will help, but try it. If not, you have other options.

I am sorry that you didn't figure anything out, but the point is that there is no single solution. There are different options and we can't say do this or do that, because it depends how you use your computer.

My idea remains the same, unless it is impossible for you, do this:
1. Write new empty msdos partition table on the hdd (NOTE: That will delete ALL DATA on it, do this only if you have nothing you want to keep).
2. Use bios boot, and not efi boot.

[23dornot23d]

A link to some more information regarding this boot problem ....

LINK (http://www.rodsbooks.com/gdisk/booting.html)

I also apologize as when I cut and pasted the commands in they came together as one.

Old Fred seemed to know his way around this problem .... we once came across it a long
time back .... and it was not as easy as it first looked .....

But if there is Data on there you need - you need to boot from the LiveCD and make sure that everything that you want is backed up .....

[rilomuse]

I just installed the 32 bit version instead and that seems to be working fine! Thanks! I had 64 bit Windows installed, so I assumed 64 bit Ubuntu would be fine.

Now I am having wireless problems even though I installed the drivers it told me, too. I think I should be able to figure this out, though.

EDIT: Nevermind, I got it! Thanks for all the help!

[23dornot23d]

Excellent - glad you sorted it out .... :D

there is a section for wireless and comms here .... to get help if you need it for that.

[drs305]

I just installed the 32 bit version instead and that seems to be working fine!

Glad it's working for you now. If you ever run the boot info script again would you mind posting it here? I'm curious to see what changed regarding EFI - something a lot of us don't know much about...

Happy Ubuntu-ing !

[oldfred]

Only the newest test/git version of the Boot info script parses efi partitions. It is in Boot Repair as the default or you have to download from the git direct download. Gert has not updated from version 60 yet.

wget -O bootinfoscript 'http://bootinfoscript.git.sourceforge.net/git/gitweb.cgi?p=bootinfoscript/bootinfoscript;a=blob_plain;f=bootinfoscript;hb=HE AD'
chmod a+x bootinfoscript
sudo bash bootinfoscript

I cannot tell if the OP was booting from efi or just had gpt partitioning and was booting from the MBR. If gpt & MBR, there is no room for the core.img, so it installs like a partition install with blocklists. To avoid the blocklists you have to create a bios_grub 1MB partition somewhere on the drive. If booting with efi, you do not have a bios_grub partition but the efi partition has to be the first partition.
