I am getting these errors when grub.efi is started but before the menu
comes up :-
error: no such device found
(3 times)
error: no suitable mode found
error: no video mode activated
using this config :-
insmod efi_gop
insmod efi_uga
insmod font
if loadfont ${prefix}/unifont.pf2
then
insmod gfxterm
set
gfxmode="1280x800x32,1024x768x32,800x600x32,640x480x32,1280x800,1024x768,800x600,640x480"
set gfxpayload=keep
terminal_output gfxterm
set color_normal=light-blue/black
set color_highlight=light-cyan/blue
insmod png
background_image ${prefix}/archlinux.png
fi
insmod part_gpt
insmod fat
insmod ext2
set timeout=5
set default=0
search --file --set=arch64 --no-floppy /vmlinuz26
set _kernel_flags="nomodeset add_efi_memmap"
set _rootfstype="ext4"
menuentry "Arch Linux 2.6.35.3-ARCH" {
linux (${arch64})/vmlinuz26
root=/dev/disk/by-uuid/0cc6e472-7f98-42ff-b7f3-309b641377ad
rootfstype=${_rootfstype} ro ${_kernel_flags}
initrd (${arch64})/kernel26.img
}
menuentry "Arch Linux 2.6.35.3-ARCH Fallback" {
linux (${arch64})/vmlinuz26
root=/dev/disk/by-uuid/0cc6e472-7f98-42ff-b7f3-309b641377ad
rootfstype=${_rootfstype} ro ${_kernel_flags}
initrd (${arch64})/kernel26-fallback.img
}
The menu colors come up properly but no background image is shown.
While booting no kernel boot messages are displayed.
Without the gfx related lines (config file starting from "insmod part_gpt" ),
(before menu)
error: no such device found
(3 times)
(while booting)
error: no suitable mode found
Booting however
No menu color change and no kernel boot messages. I am using 64-bit
UEFI 2.1 firmware (Tianocore EDK1 DUET UEFI64). How do I resolve this?
I want to see the kernel boot messages and be able to boot into
terminal (runlevel or init 3), not particular about grub2 menu colors
or background image. Thanks in advance.
