So I installed my new Xubuntu 15.04 in EFI mode. I installed gummiboot via sudo apt-get install gummiboot and activating sudo gummiboot install. On my HP Notebook I have to enter the efi file as custom boot as described here: EFI\Boot\bootx64.efi

(Without switching to gummiboot, namely booting with EFI\ubuntu\grubx64.efi, works)

Unfortunately I get a kernel panic when trying to boot, as seen in this screenshot

enter image description here

Did I miss anything important?

It looks like the kernel options passed via gummiboot are different from those passed via GRUB. In particular, the gummiboot configuration is probably missing a root={whatever} option (where {whatever} is a description of your root filesystem, such as a UUID or device filename). See the gummiboot web page for details about gummiboot configuration files.

  • I had an error in the options flag of my config (namely an error in the root variable ;) ). It's an honor that you answered my question (as the creator of refind)- Thanks a lot! – user1252280 May 19 '15 at 21:07
