Any and all help would be so greatly appreciated. I’ve been battling with my laptop to be able to dual-boot Ubuntu Cinnamon and Windows 10 for about four days now. I’ve probably gone down five or six different rabbit-holes of troubleshooting, GRUB command-line fun, reinstalling and updating the BIOS, trying and failing to deal with VMX and locked NVram. As of now, my system boot-loops and fails to run Windows, but paradoxically I am able to get Ubuntu running, which is what I am using now.

I’ll try to provide as much relevant information here as I can:

  • Device: HP ZBook 17, gen 6
  • Primary OS: Windows 10 Home
  • Linux distro: Ubuntu Cinnamon 23.10
  • Ubuntu location: /dev/sda3
  • grub-install --version = 2.12~rc1-10ubuntu4
  • boot-repair Boot-info summary: https://paste.ubuntu.com/p/rxZ3D5GtpP/
  • I’m more than happy to provide more information as it’s requested.

As of now, I am unable to run Windows through the BIOS. If I run via the dedicated SSD as I normally do, it boot-loops, and if I try to go through any other drives it just tells me I need to install an OS. I am currently able to run Ubuntu, but only by going through the following process:

  1. Startup menu
  2. Boot configuration
  3. Boot from EFI > Ubuntu > shimx64.efi

    I encourage you to read through this Archwiki page on dualbooting – it has a lot of very helpful information on the topic.

    I was originally hoping to do it this way and be able to dual boot them, but the more I think about it the more I feel that just going straight to Linux and biting the bullet would be better in the long run, and I can flash Windows if I really need it.

    It is certainly possible to dual boot (in my experience, with the occasional headache that you may, or may not be willing to deal with) Windows and Linux, but yes, the most reliable installation would be one, or the other.

    I was trying to get GRUB to act as boot loader but for the longest time I couldn’t even get GRUB running, even with at least 5 different troubleshooting ideas

    Hrm, I’m not sure how you are going about your installation procedure. You mentioned that you are installing Ubuntu, but Ubuntu should come with Grub pre packaged. Installing Ubuntu really only requires clicking a couple buttons in the install wizard.

    but I figured out how to get Linux desktop running via shimx64.efi in the BIOS boot loader.

    Im not really familiar with shim, but, from what I understand, it’s the loader for when you have secure boot enabled, but you should have that disabled.
