Finished installing Ubuntu, in what appears to be a successful installation. However, I cannot boot into it ("No Operating System Found"). After researching, I came across this article that advises the following steps:

  1. set BIOS to allow non-EFI boot
  2. boot to Live CD
  3. make directiry /mnt/1 , mount installed partition to /mnt/1
  4. mount --bind /dev /mnt/1/dev ,same to /proc, /sys
  5. chroot /mnt/1
  6. aptitude update; aptitude purge grub-efi ; aptitude install grub-pc

Was able to create the /mnt/1/ directory, but not familiar with the "mounting procedures" described in steps 3,4,5,6. Can someone walk me through these bits?

  • That procedure will set Ubuntu to boot in BIOS/CSM/legacy mode, which might work well for you or it might just be digging yourself in deeper. Are you currently dual-booting with Windows or some other OS? If so, you should coordinate your boot modes (BIOS/CSM/legacy vs. EFI/UEFI). Posting a link to the RESULTS.txt file generated by the Boot Info Script would give the information necessary to give a better response. – Rod Smith Mar 19 '15 at 1:33
  • Not dual booting with Windows. I just want one OS (Ubuntu Linux). Have already installed Ubuntu, just can't boot into it ("Operating System Not Found"). In the process of generating the results file. Going to take a few minutes as I have to boot into the "Live CD" ... – culturalanomoly Mar 19 '15 at 1:43
  • This may be a silly question, but how do I, from Terminal, perform the following: "mount installed partition to /mnt/1" ? – culturalanomoly Mar 19 '15 at 2:04

Ended up installing an older version of Ubuntu 10.04.4 LTS - Lucid Lynx; after first disabling UEFI in the BIOS. Then, installed the latest Ubuntu 14.04.2 LTS - Trusty Tahr over it. This remedied the boot issue and am now able to boot into Ubuntu on my X120e.
