    Ubuntu install not booting from GRUB 2 in UEFI mode

    Hey everyone,

    I just got a new laptop (Medion Erazer X7821) with Windows 8 on it and wanted to dualboot with Ubuntu (note, this is a must, I will not remove Windows). When I start the installation, the Grub 2 menu appears, but no matter which option I select, the screen just goes blank and nothing happens. How can I fix this?

    Re: Ubuntu install not booting from GRUB 2 in UEFI mode

    Is this the grub from UEFI boot of live flash drive installer?

    Do you have nVidia card? Then you need nomodeset which also works for some other video issues. But some systems also need other boot parameters.

    With the UEFI grub menu, it is more like first boot after install and you have to manually edit linux line. Most show instructions show the BIOS boot which gives a menu, f6 and select nomodeset.

    From grub menu press e to edit boot stanza, scroll down to linux line and change quiet splash to nomodeset.

    Skip instructions on BIOS boot and it shows similar screens as part of a first boot.

    I have the same problem too. I changed "quiet splash" to "nomodeset".

    I don't see a black screen anymore, but the screen is all glitchy, and the laptop make an unusual humming sound

    Thanks, will try that. It was the GRUB from the USB installer by the way.
    EDIT: tried nomodeset, but it didn't work unfortunately

    Have you turned secure boot off, also turned fast boot off.

    Not familiar with Medion. What UEFI/BIOS vendor is it.
    AMI (Aptio, AMIBIOS), Phoenix (SecureCore, TrustedCore, AwardCore) or Insyde (InsydeH20).

    But I have not asked nor followed which systems use which vendor.

    It's an AMIBIOS. Videocard is Nvidia Geforce GTX 680M. Turning off secure boot makes no difference. I haven't seen an option for fastboot, but perhaps I missed it. I'll check and report back in about 10 minutes.

    EDIT: I disabled both fast and secure boot and tried things like nomodeset, noapic, and acpi_osi="Linux", but it all didn't work. BTW, thanks for all the help till now I hope the issue is resolvable, but I am growing doubtful.

    Usually that type of nVidia is Optimus or dual video which causes issues. But I do not know know exact settings to get it to work. I think some turn one or the other off to get it to boot.

    Re: Ubuntu install not booting from GRUB 2 in UEFI mode

    The laptop does indeed have two video-adapters: intel HD graphics 4000 en the NVIDIA card. But there is no option to choose between the two, or to disable one. I was wondering, would it be possible to install 12.10 in Legacy mode, then repair GRUB and get it to work in UEFI mode? It seems it worked in this thread: http://ubuntuforums.org/showthread.php?t=2100372

    But no resolution.

    Some have installed in BIOS mode and used Boot-Repair to convert to UEFI. It uninstalls grub-pc and installs grub-efi.

    Alright, I finally managed to find some time to try this. I set the BIOS to legacy mode and the Xubuntu 12.10 desktop ISO booted fine. Installation went without any problems. After that, I could boot into the new installation without any problems. I downloaded boot-repair as in the instructions, went to the advanced options and enabled the secure boot option and let it do it's job. After rebooting, I got a red screen saying there was a signature mismatch for secure boot, so I disabled it. After that, Grub came up, but I could not boot Xubuntu (although Windows booted fine from the Grub menu). I tried recovery mode, but it hangs as soon as it tries to load the initial ram disk. Could it be a driver problem or something?
