Hello, I probably have a similar or the same problem. ad GPU vs EFI If I turn on UEFI boot, the screen is reduced from fullscreen on monitor to a window on the monitor in BIOS and Grub. But I don't mind. This is probably how it works with the GPU, GOP driver and BIOS.
Furthermore, I have the correct or the same resolution as normal. I tried the variant with a secure boot ON. Windows still the same error message. error: cannot load image After restarting... Linux with debug peimage: booting a command list loader/efi/peimage.c:210:peimage NX policy violation error: cannot load image. press any key to continue... If I try to boot the Linux kernel from Grub right after the Windows boot fails, I get a message: booting a command list error: first load a kernel or loader/efi/peimage.c:829:peimage: error: cannot load multiple images I wrote something about my case here. It's just messy. https://www.reddit.com/r/Ubuntu/comments/1fz1t4z/grub_212_in_oracular_is_unable_to_boot_windows/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2084104 Title: UEFI GRUB2 enforces NX even with a non-NX shim when Secure Boot is disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/2084104/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
