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
