First Dualboot Setup

[hollow crest]

I just got it to shut down, so let's see if this can be diagnosed

It now seems to work fairly well, but it still won't boot to GRUB

I've turned off fast startup, so it can't be that

And I've disabled Secure Boot for now until I can diagnose the issue

BSOD on shutdown with dualboot setup

@hollow crest not sure if you’re still having this problem, but if you are (or having any other) lmk and i can try to help too :)

Thanks

First Dualboot Setup

[hollow crest]

alrighty
before I test if this thing can now properly dualboot Windows, I'll need a tutorial about how to install these drivers
https://github.com/aircrack-ng/rtl8812au
they're for my USB Wi-Fi dongle

Also, one more thing before I hit the sack
Attempting to shut down in Win 10 may sometimes trigger the kernel security check failure error, but it'll boot to GRUB and I can boot into Linux to shut it down there

[golden bay]

might have something to do with secure boot, but maybe the error code or a pic of the bsod could help me figure it out more

[golden bay]

you’re on kde neon right?

[hollow crest]

Yup

[hollow crest]

There doesn't seem to be a specific error code
Just the kernel security check failure error
Could logs help?

But since it boots to grub, I can at least shut it down

[golden bay]

yeah i just found a microsoft docs page on it. it can be a ton of things (almost 40) so event viewer could help figure out what's going on

[hollow crest]

As for this, I can just open up the console and paste those commands in, right?

[golden bay]

and for the driver:

sudo apt install dkms
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
git switch v5.6.4.2
sudo make dkms_install

this shouldn't have any problems...but honestly it's possible but we would need to wait and see what happens to fix anything

[golden bay]

yeah, just make sure you run sudo apt update && sudo apt upgrade first

ah wait

nevermind
it might be in the default repos already

[hollow crest]

Can I run this just to be safe?

[golden bay]

so you should be able to run this instead:

sudo apt update
sudo apt upgrade
sudo apt install rtl8812au

[golden bay]

i wouldn't recommend it. that's not even a package and won't update with the rest of your system whenever a new driver is pushed, plus god knows what issues it could have

[hollow crest]

True enough

[golden bay]

installing from your distributions default repositories is always the best option whenever possible

[hollow crest]

👍

[hollow crest]

All I know so far is that it does seem to be linked to my USB hub being plugged in during shutdown

How would I go about enabling Event Viewer

[hollow crest]

Also, attempting to run sudo apt upgrade causes it to give this

apparently, you need to use pkcon upgrade instead

What am I supposed to do now

also, those drivers are actually tons of commits ahead from the stock drivers they were forked from

[golden bay]

pkcon install rtl8812au-dkms

[hollow crest]

Nvm, I installed the drivers successfully

@hollow crest has leveled up! (11 ➜ 12)

[hollow crest]

So, how would I go about trying to fix the windows shutdown issue

[hollow crest]

Yknow, this

[hollow crest]

@golden bay haven't checked logs, but I did some testing and all the blue screens seem to happen whenever I have my WiFi dongle plugged in
Maybe it's mistaking it for bootable media?

[golden bay]

have you looked at the logs yet

[hollow crest]

not yet

[golden bay]

id do that. you should be able to filter through event viewer to see “critical” and “error” events

[hollow crest]

Been a while since I've posted here, but I have some stuff to resolve
how the hell do I resolve all of these
(except for secure boot, I know how to fix that)

The swap partition is also quite confusing, as I don't know how to flag it as encrypted while Linux is running
Is unmounting a swap partition while the system is running safe?

I've been doing my research, and apparently the tainted linux kernel is due to errors 12 and 13

I'll be checking the windows boot logs later today

@golden bay

[golden bay]

you shouldn’t need to if kde’s configs are any good. if you do, un mounting swap is fine most of the time. you can use swapoff /path/to/partition/or/file
worst that will happen is apps get killed if you’re running low on memory i guess? you can check if you are with free -h before to check and see

that security section also doesn’t matter too much right now. it’s good to have, but considering how difficult it is to sign kernel modules on ubuntu and derivs, it’s not worth it

and tainted is normal since your network driver is out of tree and unsigned

[hollow crest]

oh, I see

thanks for explaining

[hollow crest]

tried to check logs last night, and windows strangely bsod'ed

[golden bay]

did you catch the error code?

[hollow crest]

exact same error

"kernel_security_check_failure"

would it be possible to try and break into the log files outside of event viewer?

[golden bay]

afaik no
