Classy

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

At this point, I am happy with two outcomes to this scenario:

1. I am able to run my laptop with Windows 10 as the primary OS, with the ability to dual-boot to Ubuntu Cinnamon 23.10.
2. Assuming option 1 is impossible/requires a Herculean amount of work to pull off from this state, I am willing to scrub Windows 10 from my laptop and move forward with Cinnamon as my daily driver, though I am rather inexperienced in it. I can learn to move forward as I need to and run a VM or WINE for any Windows-specific processes I still need to do. But I would rather keep this option as my dead man's switch.

I just installed Ubuntu 22.04.3 LTS (Cinnamon) on an empty laptop a couple days ago and have been experimenting a lot. I'm coming from being a Windows user since I was just a little kid playing old DOS games on my grandpa's Win-98 PC back in around 2000. My daily driver is currently running Windows 10 but I am pretty adamant on not going with Win-11. I've been wanting to experiment with Linux for a while and Cinnamon so far seems like a lot of fun to navigate. Terminal is amazing. The fact that you can custom-write keyboard commands that can be hand-tailored to individual programs on your computer via the OS... that's powerful.

I have not tried running WINE yet but I plan on doing so soon. I also have not done much of anything, honestly, except for learning how to search for programs with gnome-software --search=. I have also used sudo a couple times to download software here and there, but I know I am not tackling this in as systematic of a way as I ought to be to really figure this machine out.

What are some really important basic commands I can use to start branching out into Terminal command structures and learning more about how I can edit and customize my computer? And if Cinnamon has shortfalls or weaknesses that I may run into eventually, what are some good alternative distros that I could leapfrog to eventually? I do not have any coding experience (currently), but I do consider myself a semi-power-user on Windows, having messed with CMD many times and digging through all the damn menus to access drivers and alter ports.
