I installed Ubuntu GNOME on my HP Probook 650 G1. I did this as follows:

  • Disabled secureboot
  • Disabled fastboot in w8
  • Created free space using the windows partition manager
  • Opened up the Ubuntu live environment
  • Created a swap partition and a main partition to mount /
  • Run the installer

When this was done my laptop booted in windows 8. I can enter Ubuntu via boot options (from UEFI).

I tried:

  • Checking if I really disabled secureboot and fastboot
  • Running boot-repair
  • Changing boot order (ubuntu was not listed but falls under 'OS manager' which boots windows)

Can I try something else? Ubuntu had been working before on this laptop with no troubles. When the installation broke, I completely wiped the disk and reinstalled Windows. Now this.

I solved it with the technique described by the two links olfred posted. And after that running boot-repair again with "Backup and rename Windows EFI files" as suggested by insert_name_here.

How I did it:

  • Followed the instructions from this link.

  • Ran boot repair with the "Backup and rename Windows EFI files" option.

Explanation

I first tried to overwrite the original efi files with that of ubuntu's (and GRUB) that caused my machine not to boot anymore. The manufacturers lock had to be overridden. That's when the extra option in boot-repair came in.

Thanks to all for helping.
