System Does not Boot

Sorry in a big rush today with the non-tech aspect of my life lol.
Okay this is the more detailed version:

When I turn on my laptop it makes it to the grub loader, counts down and then boots the operating system like normal. Then on the next screen its all black and it says:

Loading Linux linux-zen
Loading initial ramdisk

My system hangs at this point and doesn’t load any further.
This is something that happens with my system occasionally but powering off and powering back on usually corrects this. I think it’s probably important to know that this has happened to me after a fresh install no dual booting or fancy settings like that but a clean fresh install and after a reboot the system hangs on this screen. Again this has corrected itself in the past by powering down and back on again.

The Things I’ve tried:
Paitence, I’ve tried to walk away and come back a while later to see if it’s just taking it’s sweet time or something.

I’ve read the article here: Computer doesn’t boot, boots to a black screen, or stops at a message

This article was posted above but I may be misunderstanding the instructions. It says:

The first thing to try

Switch to a text console with CTRL+ALT+F2, log in with your normal username and password, then run a full update:

I tried doing that at the screen it is hanging on

Loading Linux linux-zen
Loading initial ramdisk

It doesn’t do anything. I don’t know when exactly to do that so that’s an issue.

So I moved on from that article to this one:

I followed this advice from that post:
The easier way to chroot is to boot into a Garuda live USB and do a grub repair from within Garuda Assistant. Then run grub-update.

In the Garuda Boot Repair assistant I’m not sure what to select to I selected “Repair GRUB configuration file”

If I needed to "Reinstall GRUB bootloader on ESP,MBR, or PBR(root)
I don’t know which setting to select MBR, root, or ESP so I left it alone.

When I type grub-update:

[garuda@garuda-lxqt ~]$ grub-update
bash: grub-update: command not found

I probably am not understanding the instructions.

and finally I tried to follow this:

You may also want to reinstall the Zen kernel from the chroot:

pacman -Syu linux-zen linux-zen-headers

But now that I’m thinking about it I’m not sure what it means by “from the chroot”
That’s how far I’ve gotten and I need help because I don’t exactly understand the instruction even though I have found them.
