Kernal or Grub doesn't take over boot process

[jwolanin]

Hey guys,

Pretty new to Linux, but I'm running into a serious issue and am unsure of what exactly is the problem.

The issue I'm running into is when I boot my personal/work laptop, the kernel dose not seem to boot up properly (most of the time). I'll get the motherboard splash screen, but than when the kernel or grub is suppose to take over the boot process, nothing happens. After disconnecting the battery from the laptop (a few time) I can FINALLY get into the desktop environment. In addition to that, I can also load grub without issue, but I know even LESS about grub commands and don't feel comfortable enough to mess around in that.

I know that there are boot error logs in "journalctl -b" and can find some other information in "/var/log/boot.log" but I don't know WHAT I'm suppose to look for in figuring out why either the kernel doesn't startup or grub doesn't startup after the motherboard is done doing it's thing.

I didn't have this issue with standard Ubuntu when I ran it (but had other issues and personally I dislike gnome's desktop, and much prefer KDE).

OS: Kubuntu x86_64
KDE Plasma Version: 6.3.4
Grub: 2.12-5ubuntu11
Kernel: Linuix 6.14.0-27-generic
Laptop: OriginPC EON16
Kubuntu is running LiveCD and not from a bootable USB (not a dual boot system)

Any help would be greatly appreciated in helping me figure out what I should be looking at.

Kubuntu is running LiveCD and not from a bootable USB (not a dual boot system)

Just to clarify:
By this I take it you (are trying to) boot from the LiveCD installer, and not a "bare metal" physical install?
Is this an actual optical disk?

If so, just use a USB stick -- it will a much more pleasant and performant as you test, and easier to re-flash.
Kubuntu is entirely identical to Ubuntu until you get to the login screen, so I suspect an optical disk issue as the first thought. BAd burn, or a slightly corrupt ISO download.

My second thought, without looking for system specs, is that this has a dedicated GPU? And it is Nvidia?
I myself have little experience with dual graphics laptops, but considering you had no issues with Ubuntu I don't think trying anything like temporarily switching to the intel iGPU via the BIOS will help here (if it isn't set to that already), but it is a troubleshooting step to consider, especially running the live session, since the open source Nvidia driver in use, likely Nouveau, is pretty crap.

My apologies, I should be more clear (work was a bit crazy had to type this up as quick as possible at the time).
It is already fully installed on a Crucial 1TB NVME. Not booting from a usb stick or cd of any kind.

This dose have a dedicated GPU.
GPU 1: NVIDIA GeForce RTX 4070 Max-Q / Mobile [Discrete]
GPU 2: Intel Arc Graphics @ 2.25 GHz [Integrated]
-- specs from "fastfetch"

Currently I'm running X.Org, I did try to switch the Nvidia drivers that where "proprietary, tested" but that literally borked my system to the point I had to reinstall Kubuntu from scratch (I did not have the time to find a tutorial on how to reinitialize X.Org in the boot process/grub).

Was hoping to attach a screen shot of the possible display drivers options, but it wont let me (understandably so).
