I recently installed Ubuntu on my PC. When I boot up my PC the regular way (e.g. pressing the power button), it shows a boot loader screen, like the problem https://www.geeksforgeeks.org/how-to-fix-minimal-bash-like-line-editing-is-supported-grub-error-in-linux/ tries to solve. I followed it but failed to find my linux partition (it showed a bunch of hd0s which are all my windows disk). I am using a workaround where I booted into the BIOS first and then entered Ubuntu from there pressing the shift button which allowed me to boot into Ubuntu or my windows without seeing the GRUB screen. How do I solve the problem without this workaround?

(I have two physical disks: one with Ubuntu and one with Windows. GRUB failed to find the one with Ubuntu so I can't boot from there. (But I think BIOS can that's how the workaround works))

(Also, I can boot into Ubuntu through the BIOS, and I did follow the last step of the tutorial. It didn't work.)

  • What brand/model system? Are both installed in UEFI boot mode? May be best to see details, use ppa version with your live installer (2nd option) or any working install, not older Boot-Repair ISO: Please copy & paste the pastebin link to the Boot-info summary report ( do not post report), the auto fix sometimes can create more issues. https://help.ubuntu.com/community/Boot-Repair – oldfred Jun 14 '20 at 03:35
  • I'm quite new to this. I'm using a Legion PC with AMD CPU and graphics. I am not sure what you mean by everything else. I didn't use boot repair, are you telling me not to? – John Hao Jun 14 '20 at 03:46
  • Is this yours, please copy clickable link in question. https://paste.ubuntu.com/p/WQmtZvqqBF/. You show UEFI Secure Boot on, which should work, but often easier with it off. But you also have Windows fast startup on. http://askubuntu.com/questions/843153/ubuntu-16-showing-windows-10-partitions & https://askubuntu.com/questions/145902/unable-to-mount-windows-ntfs-filesystem-due-to-hibernation You show only one drive, but have LDM/SFS which is proprietary to Microsoft. https://askubuntu.com/questions/482768/changing-windows-dynamic-disk-partition-to-basic-partition-and-not-the-full-driv – oldfred Jun 14 '20 at 15:25

First make sure you have disabled Legacy boot option and secure boot from BIOS settings. It's fairly easy to disable
Create live USB stick of the Ubuntu version you have installed on the system.

Boot using the live UBS stick, select Try Ubuntu option. You should have internet connectivity to perform below steps:

  • Open the terminal

  • Execute following commands.

    sudo add-apt-repository ppa:yannubuntu/boot-repair
    sudo apt-get update
    sudo apt-get install -y boot-repair && boot-repair

  • Popup will appear, select recommended repair
