@karolina2
Glad you got your system working again.

@darknomel
I do not know much about Smart Status other than green is good. So your drive seems ok.
Did you run the full fsck as I also suggested? Otherwise I am about out of ideas.
Usually not mounting relates to some partition corruption.

Hi,

I am not 100% sure - I ran the commands you had in your previous reply to me? I took screenshots and posted them in my previous reply but I don't see any errors or an indication that something is wrong.

If anyone has any suggestions, it would be great, It is imperitive that I get this machine to boot.

Kind regards,
Michael

Do you get grub menu? If so remove quiet splash and see if we can get more detail on error.
At grub menu use e for edit, scroll to linux line and edit out quiet splash and boot.
It scrolls by quickly and last lines often are not issue, but several lines above that.

Does recovery mode also give same error?

Something got screwed up on my system and I tried the repair but it said it failed here is the link to the log: http://paste.ubuntu.com/6856175/ . Can someone please help me?

You have a BIOS based install with MBR(msdos) partitions. You cannot boot in UEFI mode.
But Boot-Repair saw an efi partition in fstab and tried to reinstall grub in UEFI mode.
You need to remove efi entry in fstab. You can just add # at beginning which converts it to comment.

Or you can see if you can just get Boot-Repair to reinstall in BIOS mode. Uncheck efi.

From live installer.
sudo mkdir /mnt/sdb1
sudo mount /dev/sdb1 /mnt/sdb1
gksudo gedit /mnt/sdb1/etc/fstab
comment out efi entry and then rerun Boot-Repair.

@oldfed what exactly does "comment out efi entry" mean? Do I need to delete the entire line that starts with #UUID or just delete the /boot/efi?

[oldfred]

In fstab a # means the entire line is a comment.
If if the first character is # it is commented out, but not deleted.

Or you can just delete that line.

I cannot boot from my hard drive. When boot-repair runs, it does not provide the "Recommended Repair" option. It only has the "Create a Bootinfo summary" option. Any clues in here?... http://paste.ubuntu.com/6863830/

Thought I would try out 14.04 on a separate partition from my 12.04 install but on same SSD. When I decided to delete the install by deleting the root and home 14.04 partitions I ran into trouble. Computer booted to grub rescue which I didn't know what to do with. I then tried booting to a USB with 14.04 but got a screen saying Machine Check Error and then it reboots. I was able to boot to 12.04 using a Live DVD and using boot repair followed the recommended repair. Now Ubuntu boots correctly but my USB still boots to the Machine Check Error page and won't load Ubuntu (The USB is Easy2Boot and has multiple distros on it and I have never had any problems with it prior to this). My bootrepair info is HERE

EDIT: Not sure is the reason but I reverted to an earlier kernel and PC is now working with USB Live and I am not seeing Error message. Fingers crossed this works from now on

You have volume groups or LVM. Usually Boot-Repair installs the lvm2 driver to see your partitions, but either it did not work or your LVM is corrupted. I am not familiar with LVM and what else may be an issue.

@superfreak
You show a grub install to the MBR, but have Ubuntu in UEFI boot mode. You need to be sure you always boot in UEFI boot mode. Do not know about Easy2Boot. Is that UEFI? If not that may be an issue as it is better to always be the same. Or you did not switch back to BIOS boot mode to boot flash drive. I do not see flash drive in BootInfo report.
