Replace GRUB2 with systemd-boot on Ubuntu 18

The configuration file for Grub2 is /boot/grub/grub.cfg. However, you should not add menus to this file, because the menus will be lost when using the update-grub command. Ubuntu has a file for you to add custom menus, this file is /boot/grub/custom.cfg. You just created this file and added the menu you want So this is the 2nd time I have had a grub rescue after a Windows update install; I have dual Linux and Windows, my brother put together this PC; he fixed the issue last time, he's not around, and I would like to try to fix myself

To select a menu entry under the sub-menu Advanced options set GRUB_DEFAULT=1>3. You can now run grub2-mkconfig to generate the grub config file. On the next reboot vmlinuz-3.7.4-gentoo-5 should boot. Note: This won't change the default entry in the grub menu, i.e., the default entry will still indicate the same entry as you have right now. Press the 'c' key at the GRUB Menu to switch into 'CLI Mode'. From here you can do a wealth of things, including changing menu entry names, fixing a broken install, or booting into a custom kernel configuration. 5. 'Esc' Tap the 'Esc' key at any time to return to the main GRUB Menu screen

Use Grub Customizer to Change Boot Order & Make Windows

  1. Choose the Default OS: Change the GRUB_DEFAULT= line. By default, GRUB_DEFAULT=0 uses the first entry as the default — change the number to 1 to use the second entry, 2 to use the third entry, or so on. You could also use GRUB_DEFAULT=saved and GRUB would automatically boot the last operating system you chose each time you boot. You can also specify a label in quotes
  2. Boot Into GRUB menu The first step is to reboot into the GRUB menu. If Ubuntu 18.04 Bionic Beaver is the only operating system installed you need to keep pressing SHIFT for the GRUB menu to show up. Edit Grub Menu Using arrows select the Ubuntu menu or the menu you use to boot your system and hit the e key. This will allow you to edit the menu
  3. Boot Into Rescue Mode In Ubuntu 18.04 LTS. Boot your Ubuntu system. When Grub menu appears, choose the first entry and press e to edit. (To reach the end, just press CTRL+e or use END key or LEFT/RIGHT arrows in your keyboard)
  4. Now that we've created the backup, let's edit the values of the grub configuration file to leave the grub menu hidden at startup. Use the command below to edit grub. $ sudo gedit /etc/default/grub. You'll find something like in the screenshot below
  5. I can choose to boot into Ubuntu from Grub menu for many times, and everything is OK. But once I choose to boot into Windows Boot Manager, I will never get back Ubuntu, and the PC(Dell XPS 8500) will boot into Windows 7 directly, and no Grub menu will appear. I have re-installed Ubuntu many times, but get the same result. Any suggestions? Thanks
  6. The GRUB_DEFAULT setting allows Grub to use whatever value we save as the default kernel instead of hard-coding a default. The GRUB_SAVEDEFAULT tells Grub to set the default kernel to anything we explicitly select in a menu. The GRUB_DISABLE_SUBMENU option flattens the menu structure so that we can more easily parse it. Grub 2 does not include.
  7. Release: 18.04 Codename: bionic root@lab1:~# uname -a I want to use a specific one vmlinuz-4.15.-30-generic and have it always booting without selecting it on the GRUB menu. I also didn't want to use GRUB_DEFAULT=2 as during updates this placement of my kernel might change. A bit more control that way. OK. Lets get to it
