Note: To install grub on /dev/sda disk (instead of QEMU), use: $ sudo grub-install /dev/sda The easiest way to get a functioning GRUB image is probably with the grub-mkstandalone command: $ $HOME/local/bin/grub-mkstandalone -O x86_64-efi -o mygrub.efi configure -prefix=$HOME/local -platform=efi So a practical build may look a bit like this: $ # Next command is optionnal (languages): You will need some prerequisites installed before configuring and building, so $ sudo apt-get install build-essential autoconf automake So let's live a little and go for the (U)EFI variant. Since you will be running GRUB under QEMU, it does not really matter which of the two likely platforms ("pc" or "efi") your physical computer is running. Your mentioning of Ubuntu matches at least 3 possible options from the above, but I'm going to be boring and assume you mean x86_64/amd64. So you will need to decide which firmware platform you want to use in QEMU, which depending on your architecture can be something like However, depending on your platform, grub's default target platform may or may not be what you want. Then it is theoretically just a question of $.
GRUB2 THEMES UBUNTU CODE
Leave a comment if you have any questions.As shown on the GRUB website, the grub source code is available via git from. You may need to modify and improve the Grub2 code before using it. Use the grub-mkfont command to create font files for Grub2. If then font=unicode-small Įlif then font=DejaVuSansMono-large else font=unicode-large fi if then fontmenu="Switch to larger font" else fontmenu="Switch to smaller font" fi Available in two sizes, Small and Large, for the English language, AIO Boot uses DejaVuSansMono fonts for large sizes. FontsĪIO Boot uses Unicode fonts ( unicode.pf2) to support all 38 languages. If the Grub2 language file does not exist, the language will not be listed. This is the Grub2 script to change the background image. background_image -m normal "/AIO/grub/themes/splash.png" If you want to keep the size of the background image, add a “ normal” value for the “ -m” parameter. background_image "/AIO/grub/themes/splash.png"īy default, the wallpaper will be made to fit the screen resolution.
To display the background image for Grub2, just use the background_image command. If so then use, otherwise set by default.
If you have not run AIOCreator.exe yet, rename /AIO/grub/_grubenv to /AIO/grub/grubenv. When booting into Grub2, you just need to check the value of these variables. In the code below, I will use the save_env command to save the bg, lang and font variables to the grubenv file. Run AIOCreator.exe and change it in Settings, or boot into Grub2 and change it in the Help menu (press the z key). In this article I will share the Grub2 scripts I wrote for AIO Boot.Īfter changing the background image, language and font for Grub2, these values are saved. There are two ways that you can change the background, language, and font for the AIO Boot’s Grub2. This helps you to quickly boot into the operating system. AIO Boot has too many menus, and it has hotkeys support for quick access to a menu, the hotkey is in square brackets. It is quite nice, lightweight and of course is best suited for Grub2. Instead, you can change the background, language, and font size of Grub2.ĪIO Boot has used the default theme of Grub2 since its initial release. AIO Boot uses the Grub2 default theme for the fastest boot speed.
