I wanted to upgrade from Ubuntu 14.04 LTS to the new Ubuntu 15.04 on my Dell XPS 14 2015 Developer Edition, because most issues seemed to be fixed in the live version.

Therefore I wiped the hole disk (without doing it easier) and now the XPS isn't able to find any bootable media. Then I tried to install it with the help of this guide which gave me the hint to create a new partition table.

The installation worked fine and I saw in the live version of Ubuntu that the system and my account under /home was installed.

But the notebook still can't find any bootable media. Are there any other aspects that I didn't consider?

Update:

The problem could be solved by enabling UEFI booting in the BIOS (press F12 during the boot) and by disabling 'Legacy option ROMS'. Take a look at this DELL blog post. Follow the instructions and reinstall your system.

It is possible that GRUB is not installed or corrupted. Try installing grub again if you can login through coomand line (CTRL + ALT + F1).

  • I found this article to install GRUB on my machine. I tried the command sudo grub-install /dev/sda but I get an error: Ìnstalling for i386-pc platform grub-install: error: failed to get canonical path of '/cow' – user3147268 Jun 22 '15 at 12:54
  • @user3147268 check the following link – neha Jun 22 '15 at 13:08
  • I tried the commands under If Your Grub Partition Contains A Full OS Install: sudo mount /dev/sda1 /mnt returns that /dev/sda1 is already mounted at /mnt. Next I entered sudo chroot /mnt and I got an error: chroot: failed to run command '/bin/bash': no such file or directoy. How is possible? Currently I'm using the default bash console. – user3147268 Jun 22 '15 at 13:18

    The reference to i386-pc strongly suggests that the system was installed in BIOS/CSM/legacy mode, or at least that your recovery medium was booted that way. Chances are you should be using an EFI/UEFI-mode install instead, since that's the native mode for essentially all modern firmware. Enabling BIOS/CSM/legacy support complicates the boot path and creates opportunities for problems such as the one you describe, as covered in more detail on my Web page on the subject. – Rod Smith Jun 22 '15 at 13:22
  • @user3147268 Give it a shot to these commands. When I was in a similar situation and nothing worked ,only this solution fixed grub installation. sudo mkdir /mnt/boot sudo mount -t auto /dev/sda1 /mnt/boot sudo grub-install --root-directory=/mnt/boot --recheck /dev/sda – neha Jun 22 '15 at 13:33
  • I'll try them in a minute. As @RodSmith suggested I've changed the booting mode from BIOS to UEFI. Now I'm trying to reinstall Ubuntu. – user3147268 Jun 22 '15 at 13:37
  • Thanks for all of your help. By changing the boot mode to UEFI I was able to boot successfully after the installation. Now I only need to add some drivers for the internal WiFi card and I should ready to go. – user3147268 Jun 22 '15 at 13:43
  • I need to revoke my last update. However earlier I was able to boot successfully and enter my password to login. After trying to install the WiFi drivers I've still the same issues. – user3147268 Jun 22 '15 at 16:33
  • I found this article that describes the same issues after the installation. By trying to follow the steps (after the WiFi drivers) I entered mount /dev/mapper/ubuntu--vg-root /mnt but the shell showed an error:

    mount: special device /dev/mapper/ubuntu--vg-root does not exist

     – user3147268 Jun 22 '15 at 17:30
  • The /dev/mapper/ubuntu--vg-root device might or might not exist on your system, depending on how you installed. Specifically, that's a device filename for an LVM setup; if you didn't use LVM, your root partition will be on a regular partition, like /dev/sda2 or /dev/sda6 or something like that. More broadly, posting the RESULTS.txt file from Boot Info Script may be helpful at this point. – Rod Smith Jun 22 '15 at 17:40
  • @RodSmith was finally right. Now my XPS 13 boots fine. For more information take a look at the update section in my question above. – user3147268 Jun 23 '15 at 14:08
